A new mixed-ligand copper(I) complex [Cu(L)(PPh3)(2)] (1) of methyl 2-(2-hydroxybenzylidene)hydrazinecarbodithioate (H2L) and triphenylphosphine was prepared and identified by elemental analysis, Fourier transform infrared, Raman, H-1, C-13, P-31 NMR, and UV-Vis spectroscopy, molar conductivity, and single-crystal X-ray diffraction. The copper(I) ion in the crystal structure of (1) has a distorted tetrahedral geometry achieved by the coordination of the two phosphorus atoms of triphenylphosphine groups and a nitrogen and sulfur atom of HL-. The intramolecular O-H center dot center dot center dot N and intermolecular C-H center dot center dot center dot S hydrogen bonds stabilize the crystal network of (1). In addition to these hydrogen bonds, there are pi-pi stacking between parallel aromatic rings belonging to the triphenylphosphine groups of adjusting complexes. Three structural surveys, including coordination numbers of the copper atom, coordination modes of ligand, and all reported structures containing hydrazinecarbodithioate Schiff bases are presented.
