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).
