Abstract
In the centrosymmetric binuclear title complex, [Co2(C11H14NO2)4(C10H14N2O)2], the two CoII cations [Co⋯Co = 2.6199 (5) Å] are bridged by four 4-(diethylamino)benzoate (DEAB) anions. The four nearest O atoms around each CoII ion form a distorted square-planar arrangement, the distorted square-pyramidal coordination geometry being completed by the pyridine N atom of an N,N-diethylnicotinamide (DENA) ligand. The dihedral angle between the benzene ring and the carboxylate group is 7.06 (11)° in one of the independent DEAB ligands and 4.42 (9)° in the other. The benzene rings of the two independent DEAB ligands are oriented at a dihedral angle of 86.35 (8)°. The pyridine ring is oriented at dihedral angles of 31.43 (6) and 57.92 (7)° with respect to the two benzene rings. In the crystal, weak intermolecular C—H⋯O interactions link the molecules into a three-dimensional network. Weak C—H⋯π interactions are also present in the crystal structure.
