Özet
In the centrosymmetric binuclear title complex, [Zn-2(C11H14NO2)(4)(C10H14N2O)(2)], the two Zn-II ions [Zn center dot center dot center dot Zn = 2.8874 (3) angstrom] 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) angstrom. The dihedral angle between the benzene ring and the carboxylate group is 4.89 (6)degrees in one of the independent DEAB ligands and 7.13 (7)degrees in the other. The benzene rings of the two independent DEAB ligands are oriented at a dihedral angle of 86.58 (5)degrees. The pyridine ring is oriented at dihedral angles of 31.17 (4) and 58.38 (4)degrees with respect to the two benzene rings. In the crystal, weak intermolecular C-H center dot center dot center dot O interactions link the molecules into a three-dimensional network. Two weak C-H center dot center dot center dot pi 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).
