The Zn-II atom in the title compound, [Zn(C8H7N3O2S)-(C12H8N2)]center dot 2C(2)H(6)OS center dot H2O, is N,N '-chelated by the N-heterocycle and N, O, S-chelated by the deprotonated Schiff base in a distorted square-pyramidal enviroment. Hydrogen bonds link the mononuclear molecule, the water and the dimethyl sulfoxide (DMSO) molecules into a linear chain motif. One DMSO molecule is disordered over two positions in respect of the S atom in an approximate 1:1 ratio.

The copper(II) atoms in the two independent molecules of the title compound, [Cu(C(6)H(5)O(3))Cl(C(12)H(8)N(2))], both adopt square-pyramidal geometries. The two coordinating atoms of the two heterocyclic ligands comprise the square plane, and the chlorine atom occupies the apical position of the coordination environment.
