The structural definition of adducts of stoichiometry MX:dppx (1:1) M = CuI, AgI, X = simple anion, dppx=Ph2P(CH 2)xPPh2, x = 3-6

Single crystal X-ray structural characterizations are recorded for a wide range of adducts of the form MX:dppx (1:1)(n), M = silver(I) (predominantly), copper(I), X = simple (pseudo-) halide or oxy-anion (the latter spanning, where accessible, perchlorate, nitrate, carboxylate – a range of increasing basicity), dppx=bis(diphenylphosphino)alkane, Ph2P(CH 2)xPPh2, x = 3-6. Adducts are defined of two binuclear forms: (i) [LM(mu-X)2L], with each ligand chelating a single metal atom, and (ii) [M(mu-X)2(mu-(P-L-P?)) 2M?] where both ligands L and halides bridge the two metal atoms; a few adducts are defined as polymers, the ligands connecting M(mu-X)2M? kernels, this motif persisting in all forms. Synthetic procedures for all adducts have been reported. All compounds have been characterized both in solution (1H, 13C, 31P NMR, ESI MS) and in the solid state (IR).

Tuning chemistry of CuSCN to enhance the performance of TiO 2/N719/CuSCN all-solid-state dye-sensitized solar cell

CuSCN with enhanced p-type conductivity was prepared by replacing some of the cuprous sites by triethylamine coordinated Cu(i) with concomitant (SCN) 2 doping to introduce more holes. A compound Cu5[(C 2H5)3N]3(SCN)11 was isolated and well characterized. A 41% enhancement of energy conversion efficiency of the TiO2/N719/modified CuSCN cell from the best reported value and more than a factor of ten from bare CuSCN was achieved.

The coordination chemistry of mono and bis(di-2-pyridylamine)copper(II) complexes: Preparation, characterization and crystal structures of [Cu(L)(NO2)2], [Cu(L)(H2O)2(SO4)], [Cu(L)2(NCS)](SCN)¡¤0.5DMSO and [Cu(L)2(SCN)2]

The crystal structures of two mono(dpyam)copper(II) complexes, [Cu(dpyam)(NO2)2] (1) and [Cu(dpyam)(H2O)2(SO4)] (2) and two dithiocyanate compounds containing bis(dpyam)copper(II) units, [Cu(dpyam)2(NCS)](SCN)¡¤0.5DMSO (3) and [Cu(d- pyam)2(SCN)2] (4) have been determined by X-ray crystallography. The second orthorhombic form of the monomeric Cu(II) complex 1 was obtained by the reaction of di-2-pyridylamine (dpyam) with CuCl and NaNO2 in water-methanol solution. Each copper(II) ion in 1 exhibits a tetrahedrally-distorted square base of the CuN2O2 chromophore, with off-the-z-axis coordinated nitrito groups weakly bound in approximately axial positions. Complex 2 is an example of a polymeric copper(II) derivative containing the bidentate bridging sulfate ligand in the long-bonded axial positions. Each copper(II) ion in 2 shows an elongated tetragonal octahedral stereochemistry. The CuN4N? chromophore of 3 involves a square-based pyramidal structure, slightly distorted towards a trigonal bipyramidal stereochemistry, tau = 0.13. One of the SCN- anions is bonded to the copper(II) ion via the N atom in the axial position of the square pyramid. Complex 4 is centrosymmetric and octahedrally elongated, with the SCN- anions coordinating in axial positions via the S atom. The structures of complexes 1-4 and their ESR and electronic reflectance spectra are compared with those of related complexes.

Semiconductor nanostructures in an alumina template matrix: Micro- versus macro-scale photoelectrochemical behavior

We show herein that the photoelectrochemical behavior of a given semiconductor nanodot (p-CuSCN or n-TiO2) in an alumina template matrix, is remarkably different than that of its macro-sized counterpart. Three separate examples of this distinct difference in behavior are presented. It is shown how the photoresponse (e.g. photocurrent) may be amplified (from a low level typical of the signal emanating from a ?10-11 cm2 region corresponding to a semiconductor nanodot) by using a large number of electrically inter-connected Au nanowires to support the overlying semiconductor nanodots. The anomalous photoresponse of p-CuSCN nanodots in the template matrix was also numerically simulated by a simple parallel equivalent circuit consisting of a semiconductor and a photocapacitor. Possible practical application scenarios are finally presented for these nanostructures.

Surface properties of lead-free halide double perovskites: Possible visible-light photo-catalysts for water splitting

Halide double perovskites based on combinations of monovalent and trivalent cations have been proposed as promising lead-free alternatives to lead halide perovskites. Among the newly synthesized compounds Cs2BiAgCl6, Cs2BiAgBr6, Cs2SbAgCl6, and Cs2InAgCl6, some exhibit bandgaps in the visible range and all have low carrier effective masses; therefore, these materials constitute potential candidates for various opto-electronic applications. Here, we use first-principles calculations to investigate the electronic properties of the surfaces of these four compounds and determine, for the first time, their ionization potential and electron affinity. We find that the double perovskites Cs2BiAgCl6 and Cs2BiAgBr6 are potentially promising materials for photo-catalytic water splitting, while Cs2InAgCl6 and Cs2SbAgCl6 would require controlling their surface termination to obtain energy levels appropriate for water splitting. The energy of the halogen p orbitals is found to control the conduction band level; therefore, we propose that mixed halides could be used to fine-tune the electronic affinity.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1111-67-7, help many people in the next few years.Recommanded Product: Cuprous thiocyanate

Synthesis, characterization, spectroscopic and photophysical properties of new [Cu(NCS){(L-N)2 or (L?-N?N)}(PPh3)] complexes (L-N, L?-N?N = Aromatic nitrogen base)

The syntheses, spectroscopic characterization (IR, 1H and 31P NMR, ESI-MS) and conductivity studies of the mixed N,P-donor complexes of copper(I) thiocyanate: [Cu(NCS)(py)2-(PPh3)], (2), [Cu(NCS)(Mepy)(PPh3)]2, (3), [Cu(NCS)(phen)- (PPh3)], (4), [Cu(NCS)(bpy)(PPh3)], (5), [Cu(NCS)(bpy)-(PPh2py)], (6), [Cu(NCS)(py)(PPh2py)], (7), (py = pyridine; Mepy = 2-methylpyridine; phen = 1,10-phenanthroline, bpy = 2,2?-bipyridyl), together with single-crystal X-ray structural characterizations of 2, 3, 4 (new polymorph), 5 and 6 are reported, which provides an opportunity to study the effect of the introduction of a pair of nitrogen donors, both unidentate and chelate, on the bonding parameters of the Cu/NCS/P system. Cu-P and Cu-N2(ar) are found to be similar [2.1974(5) and 2.091(2), 2.070(1) A for py2 adduct 2, cf. 2.1748(9)-2.200(1) and 2.071(2)-2.106(4) A for the counterpart values for bidentate adducts 4-6]. However, Cu-N(CS) and Cu-N-C are 2.013(2) A and 157.4(2) for py2 adduct 2 and 1.946(2)-1.981(8) A and 166.7(2)-176.58(2) for bidentate counterparts 4-6. The change is attributed primarily to the closure in the N-Cu-N angle [99.58(8) for py2 2; 77.7(6)-80.5(3) for N?N-bidentate donors 4-6]. In consequence of the increased steric profile of the Mepy ligand, we find the stoichiometry diminished to 1:1:1, which resulted in the formation of [(Ph3P) MepyCu(NCSSCN)Cu(Mepy)(PPh3)] dimers. TDDFT/CPCM calculations were used to clarify the type of transitions involved in the UV/Vis absorption spectra, and the corresponding experimental photoemission data were acquired. The 31P CPMAS spectra of the copper derivatives exhibit distorted quartets that afford values for 1JCu,P. Furthermore, the quadrupole-induced distortion factors were calculated, and in the cases of 2, 4 and 5, the quadrupole coupling constants were obtained, on the basis of the X-ray structures.

Removal of heavy metals and cyanide from gold mine waste-water by adsorption and electric adsorption

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.
