Diaqua­Bis(2-Bromo­Benzoato-Κo)Bis­(Nicotinamide-Κn1)Zinc(Ii)

Abstract

The title ZnII complex, [Zn(C7H4BrO2)2(C6H6N2O)2(H2O)2], is centrosymmetric with the Zn atom on an inversion center. The mol­ecule contains two 2-bromo­benzoate (BB) and two nicotinamide (NA) ligands and two coordinated water mol­ecules, all ligands being monodentate. 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 NA ligands in the axial positions. The dihedral angle between the carboxyl group and the adjacent benzene ring is 31.14 (12)°, while the pyridine and benzene rings are oriented at a dihedral angle of 83.54 (5)°. In the crystal structure, O—H⋯O and N—H⋯O hydrogen bonds link the mol­ecules into infinite chains. A weak C—H⋯π inter­action is also present.
