Özet
In the centrosymmetric binuclear title complex, [Zn2 (C 11H14NO2)4 (C10H 14N2O)2], the two ZnII ions [Zn⋯Zn = 2.8874 (3) Å] are bridged by four 4-(diethyl-amino) benzoate (DEAB) ligands. The four nearest O atoms around each ZnII ion form a distorted square-planar arrangement, the distorted square-pyramidal coordination being completed by the pyridine N atom of an N,N-diethyl- nicotinamide (DENA) ligand at a distance of 2.0484 (12) Å. The dihedral angle between the benzene ring and the carboxyl-ate 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 inter-molecular C - H⋯O inter-actions link the mol-ecules into a three-dimensional network. Two weak C - H⋯π inter-actions 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). © 2009 Hökelek et al.
