Crystal structure of di­aqua­bis­(7-di­ethyl­amino-3-formyl-2-oxo-2H-chromen-4-olato-κ(2) O (3),O (4))zinc(II) dimethyl sulfoxide disolvate

The structure of the title coordination complex, [Zn(C(14)H(14)NO(4))(2)(H(2)O)(2)]·2C(2)H(6)OS, 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-β-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.
