چکیده
The title complex, {[Cu(CH(4)N(2)S)(3)]I·0.5CH(3)CN}(n), was formed by the reaction of CuI and thio-urea in acetonitrile. There are two independent Cu(I) ions in the asymmetric unit which are coordinated by two terminal and two bridging thio-urea ligands to form a one-dimensional helical chain structure progagating in the a-axis direction. Each Cu(I) ion is in a distorted tetra-hedral coordination environment. The crystal structure is stabilized by weak N-H⋯S and N-H⋯I hydrogen bonds.

Redetermination of catena-poly[[chlorido(thiourea-κS)copper(I)]-μ-thiourea-κ2 S:S] at 100 K
The structure of the polymeric title compound, [CuCl(CH(4)N(2)S)(2)](n), has been redetermined to modern standards of precision with anisotropic refinement and location of the H atoms. The previous structure report [Spofford & Amma (1970 ▶). Acta Cryst. B26, 1474-1483] is generally confirmed to higher precision [typical Cu-S bond length s.u. values = 0.005 (old) and 0.001 Å (new)]. The asymmetr...

The title compound, {[Cd(NCS)(2)(CH(4)N(2)S)(2)]·2H(2)O}(n), forms a one-dimensional chain parallel to the a axis, caused by the presence of the bridging thio-cyanate groups. Two solvent mol-ecules per complex are present in the lattice. The Cd(II) ion is situated on an inversion centre and is coordinated in a distorted octa-hedral fashion by two N and two S atoms from four thio-cyanate ligands...

The title dinuclear copper(I) complex, {[Cu(2)(C(2)H(3)N)(C(12)H(10)N(2))(C(25)H(22)P(2))(2)](BF(4))(2)}(n), contains 1,2-di-4-pyridyl-ethene, bis-(diphenyl-phosphino)methane and acetonitrile ligands. The two Cu atoms, one with an N(2)P(2) ligand set and the other with an NP(2) ligand set, are bridged by two bis-(diphenyl-phosphino)methane ligands, forming an eight-membered ring.

In the title coordination polymer, [CuBr(C(3)H(5)N(3)S)](n), the Cu(I) atom adopts a tetra-hdral CuS(2)Br(2) coordination geometry arising from two S-bonded 4-methyl-1H-1,2,4-triazole-3(4H)-thione ligands and two bromide ions. Both the S and Br atoms act as bridging ligands, connecting pairs of Cu(I) atoms and generating chains propagating in [100]. Inter-chain N-H⋯N hydrogen bonds generate lay...

The title compound, [Cu(2){SC(NH(2))NHNH(2)}(6)]I(2), was obtained by the reaction of CuI and thio-semicarbazide (TSCZ) in acetonitrile. Each Cu(I) ion is coordinated by four S atoms of the TSCZ ligands, forming a tetra-hedral geometry. Centrosymmetric dimers are formed by two coordination tetra-hedra sharing a common edge, with a Cu⋯Cu distance of 2.8236 (14) Å. The I(-) ion does not have any ...
