title: Tetra-kis[μ-4-(dimethyl-amino)benzoato-κO:O']bis-[(N,N-diethyl-nicotinamide-κN)zinc(II)].
abstract: The title mol-ecule, [Zn(2)(C(9)H(10)NO(2))(4)(C(10)H(14)N(2)O)(2)], is a centrosymmetric binuclear complex, with Zn atoms [Zn⋯Zn' = 2.8927 (4) Å] bridged by four carboxyl-ate groups from the dimethyl-amino-benzoate (DMAB) ligands. The four carboxyl O atoms around the Zn atom form a distorted square-planar arrangement; the distorted square-pyramidal coordination geometry is completed by the pyridine N atom of the N,N-diethyl-nicotinamide (DENA) ligand. The Zn atom is displaced by 0.3326 (2) Å from the plane of the four O atoms, with an average Zn-O distance of 2.0416 (12) Å. The dihedral angles between the carboxyl-ate groups and the adjacent benzene rings are 5.31 (8) and 11.00 (9)°, while the pyridine ring is oriented at dihedral angles of 66.26 (6) and 37.88 (7)° with respect to the benzene rings. Weak intra-molecular C-H⋯O and inter-molecular C-H⋯π inter-actions are present.
