Tetra­kis[μ-4-(diethyl­amino)benzoato-κ(2) O:O′]bis­[(N,N-diethyl­nicotinamide-κN (1))zinc(II)]

In the centrosymmetric binuclear title complex, [Zn(2)(C(11)H(14)NO(2))(4)(C(10)H(14)N(2)O)(2)], the two Zn(II) ions [Zn⋯Zn = 2.8874 (3) Å] are bridged by four 4-(diethyl­amino)benzoate (DEAB) ligands. The four nearest O atoms around each Zn(II) ion form a distorted square-planar arrangement, the distorted square-pyramidal coordination being completed by the pyridine N atom of an N,N-diethyl­nicotinamide (DENA) ligand at a distance of 2.0484 (12) Å. The dihedral angle between the benzene ring and the carboxyl­ate group is 4.89 (6)° in one of the independent DEAB ligands and 7.13 (7)° in the other. The benzene rings of the two independent DEAB ligands are oriented at a dihedral angle of 86.58 (5)°. The pyridine ring is oriented at dihedral angles of 31.17 (4) and 58.38 (4)° with respect to the two benzene rings. In the crystal, weak inter­molecular C—H⋯O inter­actions link the mol­ecules into a three-dimensional network. Two weak C—H⋯π inter­actions are also present. The two ethyl groups of one of the DEAB ligands are disordered over two orientations, with occupancy ratios of 0.798 (5):0.202 (5) and 0.890 (5):0.110 (5).
