The coordination polymers .infin.(1)[CuBr(1,7-phen-kappaN7)] (1a), [CuI(1,7-phen)] (2a) and [(CuI)2(1,7-phen-kappaN7)] (2b) may be prepared by treatment of the appropriate copper(I) halide with 1,7-phenanthroline(1,7-phen) in acetonitrile. 1a exhibits staircase CuBr double chains, 2 a novel quadruple CuI chains. Their thermal properties were investigatedby DTA-TG and temperature resolved powder X-ray diffraction. On heating , both 1:1 compounds decompose to 2:1 polymers and then finally to CuBr or CuI. With 4,7-phenanthroline (4,7-phen), CuBr affords both 1:1 and 2:1 complexes (5a, 5b), CuI 1:1, 2:1 and 3:1 complexes (6a, 6b, 6c) in acetonitrile at 20°C. 5a and 6a display lamellar coordination networks, with the former containing zigzag CuBr single chains, the latter 4-membered (CuI)2 rings. A second 2:1 complex .infin.(2)[(CuI)2(4,7-phen-mu-N4,N7)] (6b’) with staircase CuI double chains can be obtained by reacting CuI with 4,7-phen in a sealed glass tube at 110°C. Both 5a and 6a exhibit thermal decomposition pathways of the general type 1:1 2:1 3:1 CuX, and novel CuX triple chains are proposedfor the isostructural 3:1 polymers 5c and 6c.

A direct synthesis of carbaldehydes through intramolecular dehydrogenative aminooxygenation has been developed. The process uses a catalytic amount of copper(II) in DMF or DMA under oxygen and does not require additional oxidants (see scheme). Mechanistic studies suggest that the carbonyl oxygen atom of the aldehyde is derived from oxygen through a copper-mediated oxygen activation process via a peroxy-copper(III) intermediate. Copyright

The Cu1 cations in the title compound, [Cu(NCS)(C6C6H6- N2O)2]n, are coordinated by N atoms from each of two mirror-related nicotinamide ligands, as well as by one N atom of one thiocyanate ligand and one S atom of a symmetry-related thiocyanate ligand, within a slightly distorted tetrahedron. The Cu1 cations and the thiocyanate anions are located on a crystallographic mirror plane and the nicotinamide ligands occupy general positions. The Cu1 cations are connected by the thiocyanate anions to form chains in the direction of the crystallographic a axis. These chains are connected by hydrogen bonds between the amide H atoms and the O atoms of adjacent nicotinamide ligands, to give a three-dimensional structure.

Chemistry graduates have much scope to use their knowledge in a range of research sectors, including roles within chemical engineering, chemical and related industries, healthcare and more. Application of 1111-67-7. 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.

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.

Solution-processed CuSCN serving as hole transport, electron reflecting layer (HTL, ERL) and Cu dopant source for CdSe/CdTe thin-film solar has demonstrated high power conversion efficiency (PCE) of ~17%. Two types of solvent, diethyl sulfide (DES) and aqueous ammonia (NH4OH), are explored to deposit CuSCN on CdTe, and both can enhance the performance of CdSe/CdTe solar cells. However, NH4OH solvent is less toxicity, leading to a smoother surface than DES solvent, enabling the deposition of ultra-thin CuSCN layer and avoiding the high cost of DES. Temperature-dependent current-voltage (J-V-T) and capacitance-voltage (C-V-T) measurements reveal that the use of CuSCN HTL increases hole concentration in CdTe absorber and significantly reduces back-contact barrier height. High power conversion efficiency is achievable with the optimal thickness of the CuSCN layer. Our results demonstrate solution-processed CuSCN HTL for enhancing the efficiency and reducing the cost of CdTe thin-film solar cells.

Electric Literature of 1111-67-7, With the volume and accessibility of scientific research increasing across the world, it has never been more important to continue building, we’ve spent the past two centuries establishing. Mentioned the application of 1111-67-7, Name is Cuprous thiocyanate.

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.
