Summary: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-chlorotheophylline (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 molecules. The crystal packing is stabilized by hydrogen bonds involving deprotonated HCt ligands, coordinated water molecules and uncoordinated solvent water molecules.
