Abstract: In the title compound, [Cu(C₃H₄O₄)(C₁₂H₈N₂)(H₂O)]·1.5H₂O, there are two complex molecules and three uncoordinated water molecules in the asymmetric unit. In both complex molecules, the Cu atom is five-coordinated by one bidentate 1,10-phenanthroline molecule, one bidentate malonate dianion and one water molecule, resulting in a distorted square-based pyramidal CuN₂O₃ chromophore. The structure is stabilized by O-HO hydrogen bonds involving both the coordinated and uncoordinated water molecules.
