Copper complexes of 1,3-bis(2-pyridyl)-1-thiapropane (bpt) and pyridine-2(1H)-thione. Crystal structure of [{Cu(μ-O2CMe)2(bpt)}2 ] and metal-promoted cleavage of bpt

Bis(2,2′-bipyridine)nitratocopper(II) nitrate

“…The preparation of the title compound was carried out under a dinitrogen atmosphere. To a stirred solution of [Cu(NO 3 )(SC 5 H 4 NH) 2 ] (0.26 g, 0.74 mmol), prepared according to the literature procedure of Davies et al (1997), in MeOH (25 ml) was added bipyridine (bipy; 0.13 g, 1.20 mmol). The mixture was stirred for 20 h and then boiled under re¯ux for 1 h, giving a green solution.…”

Di- and tri-organotin(IV) complexes of the new bis(1-methyl-1H-imidazol-2-ylthio)acetate ligand and the decarboxylated analogues

“…In recent years, a number of authors [25][26][27][28][29][30][31][32][33][34] have synthesized S,N-ligands of the type (CH 2 ) n (SAz) 2 based on a nitrogenated aromatic ring system such as benzimidazole or pyridine. These ligands are able to coordinate by both S and the neighbouring N atom, and hence to form stable chelate rings of five or more atoms [35][36][37][38][39][40][41].…”

Dynamic combinatorial chemistry in a solvothermal process of Cu(i,ii) and organosulfur ligands

“…The [Cu 2 (m-Hpyt-kS:kS) 2 (Hpyt-kS) 4 ] 2+ structural unit has been previously reported as chloride, bromide and p-tolylsulfonate salts. 31, 32 The analysis of the crystal structure of these compounds reveals some subtle differences between them and compound 1. The intradimer Cu ◊ ◊ ◊ Cu distances in compound 1 are similar to that found in the p-tolylsulfonate analogue, 2.744(1) A ˚, but those for the chloride and bromide salts are significantly longer, 2.950(2) and 2.907(2) A ˚.…”
