Diaqua­Bis(2-Bromo­Benzoato-Κo)Bis­(N,N-Diethyl­Nicotinamide-Κn 1)Nickel(Ii)

Abstract

In the monomeric centrosymmetric title NiII complex, [Ni(C7H4BrO2)2(C10H14N2O)2(H2O)2], the NiII ion is located on an inversion center. The asymmetric unit contains one 2-bromo­benzoate ligand, one diethyl­nicotinamide (DENA) ligand and one coordinated water mol­ecule. The four O atoms in the equatorial plane around the NiII ion form a slightly distorted square-planar arrangement, while the slightly distorted octa­hedral coordination is completed by two N atoms of two DENA ligands in the axial positions. The dihedral angle between the benzene ring and the attached carboxyl­ate group is 87.73 (15)°, while the pyridine and benzene rings are oriented at a dihedral angle of 42.48 (7)°. In the crystal structure, O—H⋯O hydrogen bonds link the mol­ecules into a two-dimensional network parallel to (10). In addition, C—H⋯O hydrogen bonds are observed.
