Reactions of (Et4N)[Tp*WS3] [Tp*is hydridotris(3,5-di-methyl-pyrazol-1-yl)borate] with CuSCN in MeCN in the presence of melamine afforded the title neutral dimeric cluster [Cu 4W2(C15H22BN6) 2(NCS)2S6(C2H3N) 2] or [Tp*W(2-S)2(3-S)Cu(2-SCN)(CuMeCN)]2, which has two butterfly-shaped [Tp*WS3Cu2] cores bridged across a centre of inversion by two (CuSCN)- anions. The S atoms of the bridging thio-cyanate ligands inter-act with the H atoms of the methyl groups of the Tp*units of a neighbouring dimer to form a C-H…S hydrogen-bonded chain. The N atoms of the thio-cyanate anions inter-act with the H atoms of the methyl groups of the Tp*units of neighbouring chains, affording a two-dimensional hydrogen-bonded network.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about !, category: copper-catalyst

Mentioned the application of 1111-67-7, Name is Cuprous thiocyanate.

The reaction of cis-1,2-bis(diphenylphosphino)ethylene (dppet) with CuX (X = CN, SCN) in 1:1 M molar ratio in DCM-MeOH (50:50 V/V) under refluxing conditions gave two dimeric Cu(i) complexes, viz. [Cu2(mu-CN)2(kappa2-P,P-dppet)2] (1) and [Cu2(mu2-SCN)2(kappa2-P,P-dppet)2] (2). These complexes have been characterized by elemental analyses, IR, 1H and 31P NMR, and electronic absorption spectroscopies, and ESI-MS. The molecular structure of 2 was confirmed by single crystal X-ray diffraction, which indicated that 2 exists as a centrosymmetric dimer in which the two copper centers are bonded to two dppet ligands and two bridging thiocyanate groups in a mu2-manner. The electrochemical properties of 1 and 2 were studied by cyclic voltammetry. Both the complexes exhibited strong luminescence properties in the solution state at ambient temperature. Both the complexes were found to be efficient catalysts for the conversion of terminal alkynes into propiolic acids with CO2. Owing to their excellent catalytic activity, the reactions proceed at atmospheric pressure and ambient temperature (25 C). The catalytic products were obtained in excellent yields (90-97%) by using the complex loading of 1 mol%.

A total of five new CuSCN-L compounds with alkyl sulfide ligands, L = methyl sulfide (Me2S), ethyl sulfide (Et2S), isopropyl sulfide (Pri2S) or tetrahydrothiophene (THT) have been prepared and characterized. X-ray crystal structures for four of the compounds were obtained. Two compounds were collected from solutions of CuSCN in Me2S: {[Cu(SCN)(Me2S)2]}n (1a) in the form of colorless blocks and (CuSCN)(Me2S) (1b) as a white powder. Neat mixtures of CuSCN in the other alkyl sulfide ligands yielded only one product each: {[Cu(SCN)(Et2S)]}n (2); {[Cu(SCN)(Pri2S)]}n (3); and {[Cu(SCN)(THT)2]}n (4). Crystals of 2 and 4 underwent destructive phase changes at lower temperatures. Two networks types were observed: 1:2 decorated 1-D chains (1a and 4) and 1:2 decorated 1-D ladders (2 and 3). Further network formation through bridging of the organic sulfide ligands was not observed.

Synthetic Route of 1111-67-7. Introducing a new discovery about 1111-67-7, Name is Cuprous thiocyanate

In the past two decades, the vast classes of coordination polymers (CPs) and metal-organic frameworks (MOFs) have received deep attention in both the academic and industrial realms, as they can possess different functional properties of economic, technological and/or environmental interest, such as luminescence, electric conductivity, magnetism, catalytic activity, gas storage or separation, drug delivery – to mention only a few. Within this vast landscape, this review proposes a survey on those transition metal containing CPs and MOFs built up with poly(pyrazole)- and poly(pyrazolate)-based ligands, in which up to three N-donor heterocyclic rings are organized on rigid or flexible cores. The overview has been restricted to the most recurrent transition metals, namely copper, zinc, cobalt, nickel, cadmium, silver and iron. For each material, mentioning of the synthetic method(s) yielding to its isolation is complemented by a description of its thermal behaviour, of the main structural aspects and, whenever investigated, of its functional properties.

Poly (3,4-ethylenedioxythiophene) polystyrene sulphonate (PEDOT:PSS) is the most widely used hole transporting layer (HTL) in planar perovskite solar cells, which shows excellent optical, electrical properties and good compatibility with low temperature, solution and flexible processing. Nevertheless, the acidic and hygroscopic property of PEDOT:PSS restricts its film conductivity and leads to the degradation of device stability. Herein, for the first time, we introduce the unprecedentedly zero-dimensional dopant of carbon nano-onions (CNOs) and the functionalized oxidized carbon nano-onions (ox-CNOs) to modify the PEDOT:PSS HTL. Besides the merits of high conductivity and suitable energy level, the CNOs and ox-CNOs modified PEDOT:PSS HTLs could provide a superior perovskite crystalline film with large-scale grains and orderly grain boundaries exhibiting a high surface tension with the hydrophobic property, resulting in a significant enhancement of PCE from 11.07% to 15.26%. Moreover, by suppressing the corrosion effect of PEDOT:PSS on ITO electrode, a dramatic improvement in the device stability has also been obtained.

Construction of a semiconductor – dye heterostructure of the configuration n-TiO2/D1/p-CuSCN/D2/p-CuSCN/D 3/p-CuSCN. (n-TiO2 is the nanocrystalline TiO2 film deposited on conducting glass, p-CuSCN = ultra-thin (?2 nm) layers of Cu(I) thiocyanate, p-CuSCN = thick layer of p-CuSCN, D 1 = Fast Green, D2 = Rhodamine 6G and D3 = Acridine Yellow) is described. It is found that this heterojunction generates photovoltaic response to light absorption by all the three dyes. The mechanism involved is suggested to be transfer of electrons to n-TiO2 and holes to p-CuSCN via tunneling. This technique could be a strategy to broaden the spectral response and enhance the efficiency of dye-sensitized solar cells.

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.Electric Literature of 1111-67-7, you can also check out more blogs aboutElectric Literature of 1111-67-7
