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

In the monomeric centrosymmetric title Ni(II) complex, [Ni(C(7)H(4)BrO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(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.
