title: Crystal structure of [1-(3-eth-oxy-2-oxido-benzyl-idene-κO (2))-4-phenyl-thio-semicarbazidato-κ(2) N (1),S](tri-phenylphosphane-κP)nickel(II).
abstract: In the title complex, [Ni(C16H15N3O2S)(C18H15P)], the Ni(II) atom has a distorted tetra-hedral 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 phenyl-thio-semicarbazide moiety and dihedral angles of 73.69 (11), 20.38 (11) and 71.30 (11)° with the phenyl rings of tri-phenyl-phosphane ligand. A pair of N-H⋯N hydrogen bonds generates an R 2 (2)(8) ring graph-set motif. The eth-oxy group is disordered over two positions, with site occupancies of 0.631 (9) and 0.369 (9). The mol-ecular structure is stabilized by a weak intra-molecular C-H⋯O hydrogen bond. In the crystal, weak N-H⋯N and C-H⋯π inter-actions connect the mol-ecules, forming a three-dimensional network.
