Aqua[1-(4-carboxyphenyl)-1H-imidazole-κN3](pyridine-2,6-dicarboxylato-κ3 O2, N, O6)copper(II) monohydrate

In the title complex, [Cu(C7H3NO4)(C10H8N2O2)(H2O)]center dot 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
