Abstract: The Cu^II atom (site symmetry ) in the title compound, [Cu(C₁₃H₁₀ClN₂O₃S)(C₁₃H₁₁N₂O₃S)], is N,O-chelated by the monoanionic ligands in a trans-CuN₂O₂ square-planar geometry. The 2'-(2-oxidobenzylidene)benzenesulfonohydrazide anion is disordered equallywith the chlorine-substituted 2'-(5-chloro-2-oxidobenzylidene)benzenesulfonohydrazide anion. An intermolecular N-HO hydrogen bond helps to stabilize the crystal structure.
