Diaqua[(Z)-4,4'-ethylenedipyridine N,N'-dioxide-O](malonato-²O:O)copper(II) trihydrate

M. R. Montney and R. L. LaDuca

Abstract: In the title compound, [Cu(C₃H₂O₄)(C₁₂H₁₀N₂O₂)(H₂O)₂]·3H₂O, a Cu^II center with `4+1' Jahn-Teller-distorted square-pyramidal coordination is bound by a chelating malonate dianion, two aqua ligands and a monodentate Z-4,4'-ethylenedipyridine N,N'-dioxide ligand. Three uncoordinated water molecules cocrystallize with each complex molecule. Individual molecules are connected into one-dimensional ribbons and two-dimensional sheets through extensive hydrogen-bonding patterns mediated by both aqua ligands and water molecules of crystallization.
