Tetra-kis[?-4-(diethyl-amino)-benzoato-?O:O']bis-[(N,N-diethyl-nicotinamide-?N)cobalt(II)].

ABSTRACT: In the centrosymmetric binuclear title complex, [Co(2)(C(11)H(14)NO(2))(4)(C(10)H(14)N(2)O)(2)], the two Co(II) cations [Co?Co = 2.6199?(5)?Å] are bridged by four 4-(diethyl-amino)-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-diethyl-nicotinamide (DENA) ligand. The dihedral angle between the benzene ring and the carboxyl-ate 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 inter-molecular C-H?O inter-actions link the mol-ecules into a three-dimensional network. Weak C-H?? inter-actions are also present in the crystal structure.
