Diaqua­Bis(2-Chloro­Benzoato-Κo)Bis­(N,N-Diethyl­Nicotinamide-Κn1)Nickel(II)

Abstract

In the monomeric and centrosymmetric title NiII complex, [Ni(C7H4ClO2)2(C10H14N2O)2(H2O)2], the NiII ion is located on an inversion center. The asymmetric unit contains one 2-chloro­benzoate ligand, one diethyl­nicotinamide (DENA) ligand and one coordinating water mol­ecule, the ligands being monodentate. 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 the DENA ligands in axial positions. The dihedral angle between the benzene ring and the attached carboxyl­ate group is 87.36 (10)°, while the pyridine and benzene rings are oriented at an angle of 41.90 (5)°. In the crystal structure, inter­molecular O—H⋯O hydrogen bonds link the mol­ecules into a two-dimensional network parallel to (10).
