Diaquabis(2-bromo-benzoato-κO)bis-(N,N-diethyl-nicotinamide-κN ¹)zinc(II)

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-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.
