L. Sieron

Abstract: The title compound, [Cu(mal)(pca)(H₂O)]·H₂O [mal is the malonate dianion, CH₂(COO)₂^2-, and pca is pyridine-2-carboxamide, C₆H₆N₂O), has a five-coordinated Cu atom in a distorted square-pyramidal environment, coordinated by two O atoms of the malonate ion, an O atom and an N atom of pca, and an O atom of water. An uncoordinated water molecule stabilizes the complex by participation in a hydrogen-bonding system. The crystal structure is built from layers parallel to the (111) plane.
