Abstract: In the title complex, [Cu(C7H4IO2)2(C6H6N2O)2(H2O)2], the CuII cation is located on an inversion center and is coordinated by two monodentate 2-iodobenzoate (IB) anions, two nicotinamide (NA) ligands and two water molecules in a distorted octahedral coordination geometry. The dihedral angle between the carboxylate group and the adjacent benzene ring is 32.12 (14)°, while the pyridine ring and the benzene ring are oriented at a dihedral angle of 82.02 (5)°. The coordinating water molecule links with the carboxylate group via an intramolecular O-HO hydrogen bond. In the crystal, N-HO, O-HO and weak C-HO hydrogen bonds link the molecules into a three-dimensional supramolecular network.
