Abstract

The structure of the title coordination complex, [Zn(C₁₄H₁₄NO₄)₂(H₂O)₂]·2C₂H₆OS, shows that the Zn^II cation adopts an octa­hedral geometry and lies on an inversion center. Two organic ligands occupy the equatorial positions of the coordination sphere, forming a chelate ring motif via the O atom on the formyl group and another O atom of the carbonyl group (a pseudo--diketone motif). Two water mol­ecules occupy the remaining coordination sites of the Zn^II cation in the axial positions. The water mol­ecules are each hydrogen bonded to a single dimethyl sulfoxide mol­ecule that has been entrapped in the crystal lattice.
