An unprecedented microwave C(sp(2))-S and S-S bond activation of 2,2'-dipyridyldisulfide (2-dpds) and the formation of a new architecture of coordination networks obtained by reaction of Cu(HCO(2))(2).xH(2)O with 2-dpds under solvothermal microwave conditions are reported. This unusual reaction proceeds with the partial oxidation of 2,2'-dipyridyldisulfide to sulfate. The process generates: a C...

The crystal structure of the title compound, [Cu(C(26)H(22)P(2))(2)][CuCl(2)], is composed of discrete Cu(dppey)(2)](+) cations [dppey is cis-bis-(diphenyl-phosphino)ethene] and [CuCl(2)](-) anions. The tetra-hedral Cu(P-P)(2) core of the [Cu(dppey)(2)](+) cation is distorted, with Cu-P bond lengths ranging from 2.269 (1) to 2.366 (1) Å. The five-membered -Cu-P-CH=CH-P- rings adopt envelope con...

Solvothermal reactions of [Et(4)N][Tp*WS(3)(CuCl)(3)] (1) (Tp* = hydridotris(3,5-dimethylpyrazol-1-yl)borate) with CuCN and KCu(CN)(2) afforded two [Tp*WS(3)Cu(3)]-based coordination polymers [Tp*WS(3)Cu(3)(μ(3)-DMF){Cu(CN)(3)}](2) (2) and K[Tp*WS(3)Cu(3)(μ(3)-DMF){Cu(2)(CN)(4.5)}](2) (3). The third-order NLO and PL responses of 1 were activated and greatly amplified through its assembly via th...

The title complex, [Cu(2)I(2)(C(18)H(12)N(6)S(2))(2)](n), contains a Cu(2)I(2) core with a Cu-Cu distance of 2.6935 (14) Å. The Cu(I) atom is coordinated by two bridging 4,4'-di-3-pyridyl-2,2'-disulfanediyldipyrimidine ligands and two bridging I atoms, forming a double chain.

Thrombosis disease has been the leading cause of morbidity and mortality worldwide. In the discovery of antithrombotic agents, three complexes of Cu(2+) and repetitive arginine-glycine-aspartic acid (RGD) sequences, Cu(II)-Arg-Gly-Asp-Ser-Arg-Gly-Asp-Ser (Cu[II]-4a), Cu(II)-Arg-Gly-Asp-Val-Arg-Gly-Asp-Val (Cu[II]-4b), and Cu(II)-Arg-Gly-Asp-Phe-Arg-Gly-Asp-Phe (Cu[II]-4c), were previously repor...

In this work, ultra-small Cu(2)O nanoparticles have been loaded on TiO(2) nanosheets with {001} facets exposed through a one-pot hydrothermal reaction. These Cu(2)O nanoparticles are well-dispersed on TiO(2) nanosheets with narrow size distributions and controllable sizes from 1.5 to 3.0 nm. Through XRD, TEM, N(2) absorption-desorption isotherms and UV-vis diffuse reflectance spectra, the Cu(2)...

The sterically shielded terpyridine was prepared, both as a new ligand and as part of the four-station nanoscaffold . Mixing of terpyridine , the parent phenanthroline and the shielded phenanthroline in the presence of Zn(2+) (1 : 1 : 1 : 1) furnished quantitatively the inverse HETTAP complex [Zn()()](2+) by self-sorting, while in the presence of Cu(+) the HETPHEN complex [Cu()()](+) was prefer...

Two C₂-symmetrical dipyrrole-polyamide dimers 2 and 3 that were tethered with triethylenetetramine and spermine, respectively, and their corresponding Cu(II) complexes 2@Cu(2+) and 3@Cu(2+), were synthesized and fully characterized. Agarose gel electrophoresis studies on pBR322 DNA cleavage indicated that both Cu(II) complexes exhibited potent DNA-cleaving activities under physiological conditi...
