(Diethylenetriamine)bis(theophyllinato)zinc(II) dihydrate

Abstract

In the title compound, [Zn(C7H7N4O2)2(C4H13N3)]·2H2O, the ZnII ion is penta­coordinated by three N atoms of the diethyl­enetriamine ligand and one N atom of each of the two theophyllinate anions in a distorted trigonal-bipyramidal geometry. The Zn—N distances range from 2.076 (3) to 2.221 (3) Å. The crystal packing is stabilized by O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds involving the theophylline and diethyl­enetriamine ligands and uncoordinated water mol­ecules.
