Bis(μ-4-hydroxy-2-oxidobenzaldehyde 4-ethylthiosemicarbazone)-κ4O2,N1,S:O2;κ4O2:O2,N1,S-bis[chloridozinc(II)] dimethyl sulfoxide trisolvate

Abstract

The two ZnII atoms in the title compound, [Zn2(C10H12N3O2S)2Cl2]·3C2H6OS, are each N,O,S-chelated by a mono-deprotonated Schiff base ligand. The Zn atoms are bridged through the phenolate O atom, leading to a central Zn2O2 core. Each Zn atom has a Cl atom in the apical position of a distorted square-pyramidal environment. Hydroxy–DMSO (DMSO is dimethyl sulfoxide) O—H...O and amide–DMSO N—H...O hydrogen bonds link the components of the crystal structure. Two of the DMSO molecules are partially disordered, with each modelled over two sites of equal weight.
