Construction of 1-2D CuI(or CuII) metal-organic architectures with metal thiocyanates and bipyridyl spacers: Syntheses, structures, and thermal properties

Three new coordination polymers based on IB metal thiocyanates, [CuII(NCS)2(DMSO)4(meso-dpb)]n (1), [Cu2II (NCS)4 (bpp)4]n (2), [CuI(NCS)(pia)]n (3) (dpb = 2,3-di(4-pyridyl)-2,3-butanediol, bpp = 1,3-bis(4-pyridyl)propane, pia = N,N?-(1,2-phenylene)diisonicotinamide), have been synthesized by the pre-assembly method and characterized by X-ray crystallography. In 1, CuII cations are bridged by meso-dpb ligands to form a one-dimensional (1D) linear chain. Compound 2 consists of 2D undulated layers of (4, 4) topology that show twofold parallel interpenetration. In the case of 3, the MI center adopts tetrahedral coordination geometry and the 2D networks are formed by organic ligand with “folding ruler-shaped” NCS–M chains. The thermal properties of 1-3 were also investigated.

Synthesis, structures, luminescence and terahertz time-domain spectroscopy of nine Cu(I) complexes with P^P ligands and 1,10-phenanthroline derivatives

Nine new copper(I) complexes bearing 1,3-bis(diphenylphosphino)propane (dppp) and 4,7-diphenyl-1,10-phenanthroline (batho) or 2,9-dimethyl-1,10-phenanthroline (neo) have been synthesized and characterized. Single crystal X-ray diffraction analysis reveals that complexes 1?4 and 6?9 are mononuclear with similar structures, while complex 5 is a binuclear structure. They display absorption around 280 nm and 410 nm, and the intensive emission in the range of 520?620 nm in the solid state occurring with lifetimes on the mus timescale indicates phosphorescence. Our TD-DFT calculations show that emission from the lowest excited triplet state T1 is of 3MLCT nature. This study manifests that these simple and long-lifetime Cu(I) systems may exhibit a similar, but more complex excited state behavior than the systems previously appreciated.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1111-67-7 is helpful to your research. 1111-67-7

Construction of two unique W/S/Cu cluster-based coordination polymers affected by pseudohalogen ligands

The pseudohalogen ligands affecting the architectures of heterothiometallic Mo(W)/S/Cu(Ag) cluster-based coordination polymers (CPs) was firstly explored. In the presence of CuCN or CuSCN with distinct pseudohalogen ligands, two unique W/S/Cu cluster-based CPs [WS4Cu3(CN)(4,4?-bipy)2]n (1, 4,4?-bipy = 4,4?-bipyridine) and {[WS4Cu4(4,4?-bipy)4][WS4Cu4(SCN)4(4,4?-bipy)2]¡¤0.5DMSO}n (2) were achieved by interdiffusion reaction of (NH4)2WS4 and 4,4?-bipy. 1 and 2 were characterized by X-ray single and powder crystal diffractions, elemental analysis, IR, UV-Vis, thermogravimetric analysis. 1 exhibits a neutral 2-D (4,4) network, fabricated by 4-connected T-shaped [WS4Cu3]+ clusters, single CN- bridges and double 4,4?-bipy bridges. While, 2 possesses an unusual 3-D fourfold non-equivalent interpenetrated architecture, consisting of two cationic and two anionic planar ‘open’ [WS4Cu4]2+ cluster-based frameworks; the cationic and anionic architectures are constructed by double 4,4?-bipy bridges and single 4,4?-bipy bridges, respectively, and all show the diamondoid topologies.
