title: Diaqua-bis(8-chloro-1,3-dimethyl-2,6-dioxo-1,2,3,6-tetra-hydro-7H-purinato-κN)copper(II) dihydrate.
abstract: The title mononuclear copper(II) complex, [Cu(C(7)H(6)ClN(4)O(2))(2)(H(2)O)(2)]·2H(2)O, based on 8-chloro-theophylline (HCt), has the Cu atom at a center of symmetry in a slightly distorted trans square-planar geometry coordinated by two N atoms of two deprotonated HCt ligands and two O atoms of water mol-ecules. The crystal packing is stabilized by hydrogen bonds involving deprotonated HCt ligands, coordinated water mol-ecules and uncoordinated solvent water mol-ecules.
