Crystal structure of [1-(3-ethoxy-2-oxidobenzylidene-κO2)-4-phenylthiosemicarbazidato-κ2N1,S](triphenylphosphane-κP)nickel(II)

Abstract

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 R 2 2(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.
