In the monomeric title compound, [Cu(C4H4O 5)(C6H6N2O)(H2O)] ·1.5H2O, the CuII cation is bound in a square-pyramidal coordination to a tridentate oxydiacetate (ODA) ligand, a monodentate pyridine-3-carboxamide (p3ca) ligand and one aqua ligand, where the two organic ligands form the basal plane and the water O atom occupies the unique apical site. The ODA ligand presents a slight out-of-plane puckering in its central ether O atom, while the p3ca ligand is essentially planar. The availability of efficient donors and acceptors for hydrogen bonding results in the formation of strongly linked hydrogen-bonded bilayers parallel to (101), with an inter-planar distance of 3.18 (1) Å and a stacking separation between the bilayers of 3.10 (1) Å, both of them governed by extended π-π inter-actions. The disordered nature of the solvent water mol-ecules around inversion centres is discussed. The monoaqua compound is compared with the octa-hedral diaqua nalogue, [Cu(C4H4O 5)(C6H6N2O)(H2O) 2], eported recently [Perec & Baggio (2009). Acta Cryst. C65, m296-m298]. © 2010 International Union of Crystallography.
