Diaqua-bis-(2-iodo-benzoato-?O)bis-(nicotinamide-?N(1))copper(II).

ABSTRACT: In the title complex, [Cu(C(7)H(4)IO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], the Cu(II) cation is located on an inversion center and is coordinated by two monodentate 2-iodo-benzoate (IB) anions, two nicotinamide (NA) ligands and two water mol-ecules in a distorted octa-hedral coordination geometry. The dihedral angle between the carboxyl-ate 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 mol-ecule links with the carboxyl-ate group via an intra-molecular O-H?O hydrogen bond. In the crystal, N-H?O, O-H?O and weak C-H?O hydrogen bonds link the mol-ecules into a three-dimensional supra-molecular network.

Intra-molecular O-H?O hydrogen bonds link the water mol-ecules to the carboxyl-ate groups. The dihedral angles between the carboxyl-ate groups and the adjacent benzene rings are 4.6?(3) and 3.7?(2)°, while the pyridine rings and the benzene rings are oriented at dihedral angles of 6.82?(11) and 3.63?(14)°. In the crystal, inter-molecular O-H?O hydrogen bonds link the mol-ecules into chains propagating along [010]. C-H?O inter-actions and a ?-? contact between the pyridine rings [centroid-centroid distance = 3.469?(2)?Å] are also observed.
