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).
