Abstract: In the title centrosymmetric mononuclear Ni^II compound, [Ni(C₈H₅O₃)₂(C₁₀H₁₄N₂O)₂(H₂O)₂], the central Ni^II atom is coordinated by two O atoms from two 4-formylbenzoate (FOB) ligands, two O atoms from two water molecules and two N atoms from two diethylnicotinamide (DENA) ligands. The coordination geometry is slightly distorted octahedral, with four O atoms in the equatorial plane and two N atoms in axial positions. Intramolecular O-HO hydrogen bonds are observed. In the crystal structure, molecules are linked into chains along the a axis by intermolecular O-HO hydrogen bonds. The structure is further stabilized by - interactions between the pyridine rings of DENA units, with a centroid-centroid distance of 3.668 (2) Å.
