Crystal structure of diaquabis(7-diethylamino-3-formyl-2-oxo-2H-chromen-4-olato-κ2 O 3,O 4)zinc(II) dimethyl sulfoxide disolvate

چکیده
The structure of the title coordination complex, [Zn(C14H14NO4)2(H2O)2]·2C2H6OS, shows that the Zn(II) cation adopts an octa-hedral 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 mol-ecules occupy the remaining coordination sites of the Zn(II) cation in the axial positions. The water mol-ecules are each hydrogen bonded to a single dimethyl sulfoxide mol-ecule that has been entrapped in the crystal lattice.
