Bis(4-ethylbenzoato-kappa O)bis(nicotinamide-kappa N-1)zinc(II)

The title Zn II complex, [Zn(C9H9O2)(2)(C6H6N2O)(2)], contains two 4-ethylbenzoate and two nicotinamide monodentate ligands, leading to a distorted tetrahedral coordination of the Zn-II ion. The dihedral angles between the carboxylate groups and the adjacent benzene rings are 10.33 (13) and 2.38 (11)degrees, while opposite pyridine and benzene rings are oriented at dihedral angles of 68.46 (5) and 81.09 (6)degrees. In the crystal, intermolecular N-H center dot center dot center dot O hydrogen bonds link the molecules, forming a three-dimensional network. C-H center dot center dot center dot O interactions also occur as well as two weak C-H center dot center dot center dot pi interactions involving the benzene rings.
