Diaqua-bis(2-chloro-benzoato-?O)bis-(N,N-diethyl-nicotinamide-?N)nickel(II).

ABSTRACT: In the monomeric and centrosymmetric title Ni(II) complex, [Ni(C(7)H(4)ClO(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-chloro-benzoate ligand, one diethyl-nicotinamide (DENA) ligand and one coordinating water mol-ecule, the ligands being monodentate. 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 the DENA ligands in axial positions. The dihedral angle between the benzene ring and the attached carboxyl-ate group is 87.36?(10)°, while the pyridine and benzene rings are oriented at an angle of 41.90?(5)°. In the crystal structure, inter-molecular O-H?O hydrogen bonds link the mol-ecules into a two-dimensional network parallel to (10).
