Bis[4-hydroxy-N′-(4-methoxy-2-oxido-benzylidene-κO2)benzohydrazidato-κ2O,N′]cadmium(II) dimethyl sulfoxide disolvate

The metal atom in the title compound, [Cd(C15H13N2O4)(2)]center dot-2C(2)H(6)OS, is twice O,N,O'-chelated by two symmetry-related Schiff base ligands to define a trans-N2O4 octahedral geometry. Each anion occupies meridional sites of the octahedron; the metal atom lies on a special position of site symmetry 2. The dimethyl sulfoxide molecule is a hydrogen-bond acceptor to the -NH- unit, and O-H center dot center dot center dot O hydrogen bonds link molecules into a supramolecular chain.
