Abstract: In the monomeric and centrosymmetric title Ni^II complex, [Ni(C₇H₄ClO₂)₂(C₁₀H₁₄N₂O)₂(H₂O)₂], the Ni^II 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 Ni^II 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-HO hydrogen bonds link the molecules into a two-dimensional network parallel to (10).
