Bis(μ-4-formyl-benzoato-κ(2) O:O')bis-[(4-formyl-benzoato-κ(2) O,O')bis-(iso-nicotin-amide-κN (1))copper(II)].

ABSTRACT: The asymmetric unit of the centrosymmetric dinuclear title compound, [Cu2(C8H5O3)4(C6H6N2O)4], contains one half of the complex mol-ecule. The Cu(II) atoms are bridged by the carboxyl-ate groups of two 4-formyl-benzoate (FOB) anions. Besides the two bridging FOB anions, one additional chelating FOB anion and two isonicotinamide (INA) ligands complete the distorted CuN2O4 octa-hedral coordination of each Cu(2+) cation. Within the asymmetric unit, the benzene and pyridine rings are oriented at dihedral angles of 25.1 (3) and 12.6 (3)°, respectively. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π contacts between the pyridine rings [shortest centroid-centroid distance = 3.821 (3) Å] may further stabilize the crystal structure.
