Abstract
In the title complex, [Cu(C7H3NO4)(C10H8N2O2)(H2O)]·H2O, the CuII ion is in a slightly distorted square-pyramidal geometry. Two carboxylate O atoms and one pyridine N atom from a pyridine-2,6-dicarboxylate ligand chelate the CuII ion, forming two stable five-membered metalla rings. One imidazole N atom from a 1-(4-carboxyphenyl)imidazole ligand and one water molecule complete the five-coordination. O—H⋯O hydrogen bonds involving the coordinated water molecules and carboxylate groups link the complex molecules into chain-containing dinuclear macrocycles. O—H⋯O hydrogen bonds involving the uncoordinated water molecules link the chains into a layer extending parallel to (10).
