Tetrakis[l-4-(diethylamino)benzoato-κ ²O:O′]bis[(N, N-diethylnicotinamide-κN¹)cobalt(II)]

In the centrosymmetric binuclear title complex, [Co₂(C ₁₁H₁₄-NO₂)₄(C₁₀H ₁₄N₂O)₂], the two Co^II cations [Co⋯Co = 2.6199 (5) Å ] are bridged by four 4-(diethylamino) benzoate (DEAB) anions. The four nearest O atoms around each Co^II 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.
