Copper thiocyanate compounds with three different oxidation states, CuI(admtrz)SCN (1), [CuI2CuII(admtrz)6 (SCN)2]-(ClO4)2 (2), and [CuII3(admtrz)4(SCN)3 (mu3-OH)(H2O)](ClO4)2 ·H2O (3), have been synthesized and characterized (admtrz = 4-amino-3,5-dimethyl-1,2,4-triazole). Compounds 1 and 3 crystallize in the space group Pbca of the orthorhombic system with eight formula units in cells of dimensions a = 8.0221(2) A, b = 32.3844(1) A, c = 13.5659(3) A, R1/wR2 = 0.0595/0.1674 for compound 1 and a = 21.501(3) A, b = 18.382(2) A, c = 21.526(2) A, R1/wR2 = 0.0638/0.1519 for compound 3. Compound 2 crystallizes in the space group C2/c of the monoclinic system with four formula units in cells of dimensions a = 18.772(4) A, b = 11.739(2) A, c = 22.838(5) A, beta = 91.11(3), R1/wR2 = 0.0482/0.1265. The layered-type structure of 1 can be regarded as constructed from the tetranuclear copper units double bridged by one of the two unique thiocyanate and admtrz ligands, which are bridged by the other unique thiocyanate ligands to form a two-dimensional layered structure along the a and b directions. The linear trinuclear copper cation in mixed-valence compound 2 consists of one two-valence copper and two one-valence copper atoms which are bridged by admtrz ligands, and the external copper(I) atoms are coordinated by terminal thiocyanate. The EPR spectra of 2 show the existence of localized mixed-valence copper ions. The triangle trinuclear copper cation in compound 3 has its Cu3 triangle capped by one apical mu3-OH group, each edge bridged by a bridging admtrz ligand and each Cu atom coordinated by a N atom from the terminal thiocyanate, while one of the three edges is further bridged by another admtrz ligand and the opposite Cu1 atom is coordinated by a water molecule. The EPR and magnetic susceptibility of compound 3 were studied, showing antiferromagnetic behavior.

Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. name: Cuprous thiocyanate. Introducing a new discovery about 1111-67-7, Name is Cuprous thiocyanate, The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis.

Controllable synthesis of uniformly disk-shaped CuS nanostructures with a narrow size distribution was realized by a lowerature (150 C) solvothermal process using polyvinyl pyrrolidone (PVP) as the surfactant. Monodispersed nanodisks of pure CuS phase with an average diameter of ca. 500 nm could be obtained at a specific S/Cu molar ratio (xS/Cu) of raw materials, which was revealed to affect the phase structure and morphology of the product but the influence of PVP content (xPVP) is limited. The CuS nanodisks have a broad absorption in the visible region and superior photocatalytic performances for the degradation of RhB whose decomposition rate reaches 93% in 2 h, indicating a potential application in the field of wastewater treatment.

The thermal decomposition of Cu2L2Cl4, Cu2L2Cl2, Cu2L2Br 2 and Co2L2Cl4 complexes (L=3,5-dimethyl-1-thiocarboxamidepyrazole) is described. The influence of the central ion to ligand mole ratio on the course of complex formation is examined in reaction of L with copper(II) chloride. In Cu(II):L mole ratio of 1:1, in methanolic solution the reaction yields to yellow-green Cu2L 2Cl4 crystals. In the filtrate a thermodynamically more stable orange Cu2L2Cl2 copper(I) complex is forming. With a Cu(II):L mole ratio of 1:2 only the latter compound is obtained. The composition and the structure of the compounds have been determined on the basis of customary methods. On the basis of FTIR spectrum of the intermediate which is forming during the thermal decomposition of Cu2L 2Cl2 a decomposition mechanism is proposed.

While the effects of structural disorder on the electronic properties of solids are poorly understood, it is widely accepted that spatially isotropic orbitals lead to robustness against disorder. In this paper, we use first-principles calculations to show that a cluster of occupied bands in the coordination polymer semiconductor beta-copper(I) thiocyanate undergo relatively little fluctuation in the presence of thermal disorder-a surprising finding given that these bands are composed of spatially anisotropic d-orbitals. Analysis with the tight-binding method and a stochastic network model suggests that the robustness of these bands to the thermal disorder can be traced to the way in which these orbitals are aligned with respect to each other. This special alignment causes strong inverse statistical correlations between orbital-orbital distances, making these bands robust to random fluctuations of these distances. As well as proving that disorder-robust electronic properties can be achieved even with anisotropic orbitals, our results provide a concrete example of when simple ‘averaging’ methods can be used to treat thermal disorder in electronic structure calculations.

The synthesis and characterization of copper (I) selenocyanate (CuSeCN) and its application as a solution-processable hole-transport layer (HTL) material in transistors, organic light-emitting diodes, and solar cells are reported. Density-functional theory calculations combined with X-ray photoelectron spectroscopy are used to elucidate the electronic band structure, density of states, and microstructure of CuSeCN. Solution-processed layers are found to be nanocrystalline and optically transparent (>94%), due to the large bandgap of ?3.1 eV, with a valence band maximum located at ?5.1 eV. Hole-transport analysis performed using field-effect measurements confirms the p-type character of CuSeCN yielding a hole mobility of 0.002 cm2 V?1 s?1. When CuSeCN is incorporated as the HTL material in organic light-emitting diodes and organic solar cells, the resulting devices exhibit comparable or improved performance to control devices based on commercially available poly(3,4-ethylenedioxythiophene):polystyrene sulfonate as the HTL. This is the first report on the semiconducting character of CuSeCN and it highlights the tremendous potential for further developments in the area of metal pseudohalides.

The synthesis and crystal structure elucidation of two novel polymeric copper(II) complexes has led us to propose a mechanism for the formation of 2-picolinic acid (pic) from di-2-pyridyl ketone (dpk) and benzoic acid from acetophenone. During studies into the interaction of copper ions with the dpk-acetophenone system, two complexes Na2(NCS)2(H 2O)[Cu(pic)2] (1) and Na2(H2O) 2[Cu(pic)2(NCS)2] (2) which contain pic coordinated to copper were isolated. The occurrence of (1) and (2) has led us to consider the Baeyer-Villiger rearrangement as a possible mechanism for the formation of (1) and (2).

BACKGROUND: Cyanide leaching is the most widely used technology in the gold industry and this process produces large amounts of waste-water requiring treatment before returning to the environment. There are several established techniques available to treat such toxic waste but all have some disadvantages. This study considers the use of electrical adsorption treatment of a gold mine waste-water containing cyanide, high copper, iron, and thiocyanate content, as well as the precipitating liquid without iron. RESULTS: A cell fitted with carbon electrodes made from low grade coal was used in this study and using an applied voltage of 2.0 V, plate spacing of 1 cm, and adsorption time of 24 h, the electric adsorption process provided good results on the raw cyanide waste-water, with observed percentage removal of total cyanide (71.14), zinc (99.52) and iron (83.28). The liquid waste, following precipitation of the raw solution with zinc sulfate, was also studied and after 5 h the percentage removals of cupric ion were 90.63, 71.49 and 90.63, respectively. Analysis showed that in the process of electric adsorption, the ions in solution interacted by directional migration, enrichment precipitation and adsorption processes. CONCLUSIONS: Electrical adsorption provides a suitable process for the treatment of waste-waters from the cyanide leaching of gold.

In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. Formula: CCuNS. Introducing a new discovery about 1111-67-7, Name is Cuprous thiocyanate

Analytical procedures based on ion chromatography utilising an anion exchange column and UV detection are described for the quantification of thiosulfate, polythionates and gold thiosulfate both in leach solutions and adsorbed on anion exchange resins. The analysis of resins involves a two step perchlorate strip, and since perchlorate is used as the chromatography eluent, the high background concentration in the sample has little effect on the retention. Results are reported for the analysis of gold thiosulfate leach solutions and it is shown that tetrathionate and pentathionate are the dominant reaction products from thiosulfate oxidation at pH 8.5 and 9, whilst trithionate and sulfate are formed at pH 10.4. An increase in thiosulfate consumption when increasing pH from 8.5 to 9 is attributed to the increase in the rate of copper(I) oxidation with increasing ammonia concentration. However, the rate of thiosulfate consumption is higher at pH 9.0 than pH 10.4, and this is explained in terms of the differing reaction products. The adsorption of thiosulfate, polythionates and gold thiosulfate onto anion exchange resins is also discussed with reference to the quantification of the equilibrium solution and resin concentration of each species. Isotherms for gold on resin vs. gold in solution are reported for solutions of various polythionate concentrations.

Reaction of copper(I) thiocyanate with 1-ethyl-2-methyl-pyrazine in acetonitrile yields the two new coordination polymers catena[(mu 2-thiocyanato-N,S)-(1-ethyl-2-methylpyrazine-N)] copper(I)(I) and poly[(di-mu2-thiocyanato-N,S)-(mu2-1-ethyl-2-methyl- pyrazine-N,N?)] di-copper(I) (II). The crystal structure of I is composed of CuSCN double chains in which each copper atom is connected to two thiocyanate anions and two 1-ethyl-2-methyl-pyrazine ligands. In this compound only one nitrogen atom of the 1-ethyl-2-methyl-pyrazine ligand is involved in copper coordination. The crystal structure of II is composed of CuSCN layers that are connected by the N-donor ligands via mu-N,N? coordination into a three-dimensional coordination network. On heating the amine rich compound I loses half of the ligands and transforms into the amine-poorer compound II which occurs as an intermediate. Compound II decomposes on further heating to CuSCN. This reaction was investigated using simultaneous differential thermoanalysis and thermogravimetry coupled with mass spectroscopy and temperature dependent X-ray powder diffraction.
