Abstract: The two Zn^II 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-HO and amide-DMSO N-HO 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.
