| Summary: | In the title complex, [Ni(C16H15N3O2S)(C18H15P)], the NiII atom has a distorted tetrahedral coordination geometry, comprised of N, S, O and P atoms of the tridentate thiosemicarbazide ligand and the P atom of the triphenylphosphane ligand. The benzene ring makes a dihedral angle of 53.08 (11)° with the phenyl ring of the phenylthiosemicarbazide moiety and dihedral angles of 73.69 (11), 20.38 (11) and 71.30 (11)° with the phenyl rings of triphenylphosphane ligand. A pair of N—H...N hydrogen bonds generates an R22(8) ring graph-set motif. The ethoxy group is disordered over two positions, with site occupancies of 0.631 (9) and 0.369 (9). The molecular structure is stabilized by a weak intramolecular C—H...O hydrogen bond. In the crystal, weak N—H...N and C—H...π interactions connect the molecules, forming a three-dimensional network.
