Aquamalonato(1,10-phenanthroline)-copper(II) sesquihydrate

In the title compound, [Cu(C3H4O4)(C12H8N2)(H2O)]center dot 1.5H(2)O, 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-H center dot center dot center dot O hydrogen bonds involving both the coordinated and uncoordinated water molecules.
