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 (10overline{1}).

The title Ni II complex, [Ni(C 7 H 4 ClO 2) 2 (C 6 H 6 N 2 O) 2 (H 2 O) 2 ], is centrosymmetric with the Ni atom located on an inversion centre. The molecule contains two 2-chlorobenzoate (CB) and two nicotinamide (NA) ligands and two water molecules, all ligands being monodentate. The four O atoms in the equatorial plane around the Ni atom form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by the two N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl group and the adjacent benzene ring is 29.48 (16) , while the pyridine and benzene rings are oriented at a dihedral angle of 83.16 (5). In the crystal structure, O-HÁ Á ÁO and N-HÁ Á ÁO hydrogen bonds link the molecules into infinite chains.-Contacts between the benzene and pyridine rings [centroid-centroid distance = 3.952 (1) Å ] may further stabilize the crystal structure. There is also a C-HÁ Á Á interaction. metal-organic compounds m466 Hö kelek et al.
