Abstract

In the centrosymmetric title complex, [Zn(C(7)H(4)BrO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Zn(II) atom is located on an inversion center. The asymmetric unit contains one 2-bromo-benzoate (BB), one diethyl-nicotinamide (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 octa-hedral 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)°, while the pyridine and benzene rings are oriented at a dihedral angle of 44.07 (6)°. In the crystal structure, O-H⋯O hydrogen bonds link the mol-ecules into infinite chains.
