Three new copper(I) thiocyanato complexes [Cu(NCS)L](n) (L = methyl nicotinate 1, ethyl nicotinate 2), and [HL] [Cu(NCS)2] (HL = H-ethyl isonicotinate 3), have been prepared and characterized by spectroscopic and crystallographic methods. All three complexes display MLCT transitions in the visible region, as well as visible solid state emission spectra at room temperature. Their IR spectra are measured and discussed. In the structure of 1 each copper atom links two S atoms from two mu-S,S,N thiocyanato ligands and two nitrogen atoms from a pyridine nucleus and from a third mu-S,S,N thiocyanate group; the two S atoms bind another copper atom forming a Cu2S2 cyclic unit. The ladder propagates along the a axis of the unit cell. The structure of 2 features CuS2N2 coordination with approximate tetrahedral environment, mu-S,S,N bridging thiocyanate groups giving rise to corrugated layers at y = 1/4. Complex 3 consists of an N-protonated ethyl isonicotinate cation and a polymeric [Cu(NCS)2]- anion. Each trigonal planar copper atom in the anion is coordinated by two S atoms from a mu-S,N thiocyanate bridge and a terminal S-thiocyanate group, and the third site is occupied by the end nitrogen of a mu-S,N thiocyanate bridge. The terminal NCS group forms a hydrogen bond of the type N-H···N with an N-H group of the [HL]+ cation. The planar ribbon which runs in the a direction is further stabilized by N-H···O hydrogen bonds. (C) 2000 Elsevier Science Ltd.

Poly(methyl methacrylate) (PMMA) was synthesized via atom transfer radical polymerization (ATRP). As a catalyst copper(I)thiocyanate (CuSCN) was used with N-n-pentyl-2-pyridylmethanimine as a ligand. Infrared spectroscopy and matrix assisted laser desorption ionization time-of-flight mass spectrometry were used to characterize the synthesized polymers. From this it was clear that at least to some extent thiocyanate was present as end groups of the PMMA chains. This observation is discussed in view of a phenomenon called halogen exchange, which has been reported before for bromine/chlorine exchange in ATRP.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Synthetic Route of 1111-67-7, you can also check out more blogs aboutSynthetic Route of 1111-67-7

Iron(II) complexes with N-substituted bidentate and tetradentate thiosalicylideneimines can be prepared by the reaction of bis(thiosalicylaldehydato)iron(II) with appropriate primary amines.The bidentate compounds show S = 2 spin states while a number of the tetradentate compounds have the unusual S = 1 state.The tetradentate complexes react with CO to form monocarbonyl complexes and with O2 to form FeIII mu-oxo-bridged derivatives.Some evidence is presented to support the preliminary formation at low temperatures of a dinuclear iron(III) peroxo-species as the precursor of the mu-oxo-compounds.Several spin-paired FeIII compounds containing SN2-bonded tridentate ligands are also reported.

Inorganic CuSCN and organic tetrathiafulvalene derivatives (TTFs) have been exploited as hole-transport materials (HTM) in hybrid perovskite solar cells. To develop new HTM, we herein report two hybrid materials incorporating redox-active TTFs with CuSCN framework (TTFs-CuSCN). Single-crystal analysis showed that compound [Cu2(py-TTF-py)(SCN)2] (1) is three-dimensional (3D) and compound [Cu(py-TTF-py)(SCN)] (2) is two-dimensional (2D) (py-TTF-py = 2,6-bis(4?-pyridyl)tetrathiafulvalene). There are covalent coordination interactions between CuSCN and py-TTF-py and short S···S contacts between the py-TTF-py ligands for both compounds. Besides, C···S contacts exist between py-TTF-py ligands of the neighboring 2D networks in 2, which facilitate the charge transfer and supply efficient multidimensional pathways for carrier migration. As a result, 2 presented better semiconductor performance in comparison with that of 1. The performance of 2 related to the HTMs could be significantly improved by modulating the electronic state of the TTFs-CuSCN framework via oxidative doping. The iodine-doped 2D material (2-I2) gives the most excellent conductivity and carrier mobility, which might be a potential new HTM.

The meagre (structurally defined) array of 1:2 silver(I) (pseudo-)halide:unidentate nitrogen base adducts is augmented by the single-crystal X-ray structural characterization of the 1:2 silver(I) thiocyanate:piperidine (‘pip’) adduct. It is of the one-dimensional ‘castellated polymer’ type previously recorded for the chloride: ?Ag(pip) 2(mu-SCN)Ag(pip)2? a single bridging atom (S) linking successive silver atoms. By contrast, in its copper(I) counterpart, also a one-dimensional polymer, the thiocyanate bridges as end-bound SN-ambidentate: ?CuSCNCuSCN? A study of the 1:1 silver(I) bromide:quinoline (‘quin’) adduct is recorded, as the 0.25 quin solvate, isomorphous with its previous reported ‘saddle polymer’ chloride counterpart. Recrystallization of 1:1 silver(I) iodide:tris(2,4,6-trimethoxyphenyl)phosphine (‘tmpp’) mixtures from py and quinoline (‘quin’)/acetonitrile solutions has yielded crystalline materials which have also been characterized by X-ray studies. In both cases the products are salts, the cation in each being the linearly coordinated silver(I) species [Ag(tmpp)2]+, while the anions are, respectively, the discrete [Ag5I7(py)2]2- species, based on the already known but unsolvated [Cu5I 7]2- discrete, and the [Ag5I7] (?|?)2- polymeric, arrays, and polymeric [Ag5I6(quin)](?|?)-. The detailed stereochemistry of the [Ag(tmpp)2]+ cation is a remarkably constant feature of all structures, as is its tendency to close-pack in sheets normal to their P-Ag-P axes. The far-IR spectra of the above species and of several related complexes have been recorded and assigned. The vibrational modes of the single stranded polymeric AgX chains in [XAg(pip) 2](?|?) (X = Cl, SCN) are discussed, and the assignments nu(AgX) = 155, 190 cm-1 (X = Cl) and 208 cm -1 (X = SCN) are made. The nu(AgX) and nu(AgN) modes in the cubane tetramers [XAg(pip)]4 (X = Br, I) are assigned and discussed in relation to the assignments for the polymeric AgX:pip (1:2) complexes, and those for the polymeric [XAg(quin)](?|?) (X = Cl, Br) compounds. The far-IR spectra of [Ag(tmpp)2]2[Ag 5I7(py)2] and its corresponding 2-methylpyridine complex show a single strong band at about 420 cm-1 which is assigned to the coordinated tmpp ligand in [Ag(tmpp)2] +, and a partially resolved triplet at about 90, 110 and 140 cm -1 which is assigned to the nu(AgI) modes of the [Ag 5I7L2]2- anion. An analysis of this pattern is given using a model which has been used previously to account for unexpectedly simple nu(CuI) spectra for oligomeric iodocuprate(I) species.

Application of 1111-67-7, As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. In an article, once mentioned the application of Application of 1111-67-7, Name is Cuprous thiocyanate,molecular formula is CCuNS, is a conventional compound. this article was the specific content is as follows.

From solutions of CuSCN or AgSCN in pyridine, several pyridine complexes of the thiocyanates with varying compositions and crystal structures were isolated depending on the reaction conditions. In CuSCN and in the orthorhombic modification of AgSCN the SCN- anions co-ordinate to four metal atoms as 1,1,1,3-mu4 bridges, whereas the degree of bridging decreases with increasing amounts of pyridine in the polymeric complexes [Cu(SCN)(py)z] and [Ag(SCN)(py)z] (z = 1 or 2). The distorted tetrahedral co-ordination of the metal atoms is preserved by co-ordination of pyridine ligands. Especially in the heteronuclear complexes [AgCu(SCN)2(py)4], [AgCu(SCN)2(py)3] and [Ag2Cu(SCN)3(py)3], interesting variants of structures result from the different possible modes of co-ordination of the SCN- ligand and from the preferred co-ordination of the “soft” S atoms to the “soft” Ag+ ions as defined by Pearson’s hard and soft acid and base principle.

In complexes 1 and 4, hydrogen bonds CHa??X and weak interactions CHa??pi lead to the formation of chains and 2D network respectively, while complexes 2 and 3 are dinuclear. In 5-7, intramolecular hydrogen bonds link the [CuX(thione)(PPh3) 2] molecules and the solvated methanol molecules into centrosymmetric dimers. Complexes 1-5 represent first copper(I) halide complexes of HMNBT and HAMTD. The complexes 1, 5, 6 and 7 exhibit interesting fluorescence in the solid state at room temperature and their terahertz (THz) time-domain spectroscopy was also studied.
