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

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
