(anti-Chloridothiosemicabazide-κS)bis(triphenylphosphane-κP)copper(I) 0.48-hydrate

Abstract

In the mononuclear title complex, [CuCl(CH5N3S)(C18H15P)2]·0.48H2O, the CuI ion is in a slightly distorted tetra­hedral coordination geometry formed by two P atoms from two tri­phenyl­phosphane ligands, one S atom from a thio­semicarbazide ligand and one chloride anion. An intra­molecular N—H⋯N hydrogen bond [graph-set motif S(5)] stabilizes the thio­semicarbazide ligand in its anti conformation, and an intra­molecular N—H⋯Cl hydrogen bond between the hydrazine N—H group and the chloride anion influences the arrangement and orientation of the ligands around the metal center. A weak intra­molecular C—H⋯Cl hydrogen bond is also present. In the crystal, complex mol­ecules are connected through N—H⋯Cl hydrogen bonds originating from the amide –NH2 group, and through O—H⋯S and O—H⋯Cl hydrogen bonds involving the solvent water mol­ecule. Both the direct N—H⋯Cl hydrogen bonds as well as the bridging hydrogen bonds mediated by the water mol­ecule connect the complex mol­ecules into zigzag chains that propagate along [010]. The solvent water mol­ecule is partially occupied, with a refined occupancy of 0.479 (7).
