Abstract

In the centrosymmetric title complex, [Zn(C7H4BrO2)(2)(-)(C10H14N2O)(2)(H2O)(2)], the Zn-II atom is located on an inversion center. The asymmetric unit contains one 2- bromobenzoate (BB), one diethylnicotinamide (DENA) ligand and one coordinating water molecule. The four O atoms in the equatorial plane around the Zn atom form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by the two N atoms of the DENA ligands in the axial positions. The dihedral angle between the carboxyl group and the adjacent benzene ring is 85.51 (12)degrees, while the pyridine and benzene rings are oriented at a dihedral angle of 44.07 (6)degrees. In the crystal structure, O-H center dot center dot center dot O hydrogen bonds link the molecules into infinite chains.
