Diaquabis(2-bromobenzoato-κO)bis-(N,N-diethylnicotinamide-κN ¹)nickel(II)

In the monomeric centrosymmetric title Ni^II complex, [Ni(C ₇H₄BrO₂)₂(C₁₀H ₁₄N₂O)₂(H₂O)₂], the Ni^II ion is located on an inversion center. The asymmetric unit contains one 2-bromo-benzoate ligand, one diethyl-nicotinamide (DENA) ligand and one coordinated water mol-ecule. The four O atoms in the equatorial plane around the Ni^II ion form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral 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 carboxyl-ate 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 mol-ecules into a two-dimensional network parallel to (10 ). In addition, C - H⋯O hydrogen bonds are observed.
