Abstract
In the mononuclear NiII title complex, [Ni(C7H4FO2)2(C6H6N2O)2(H2O)2], the NiII atom, located on an inversion center, is coordinated by two nicotinamide and two 4-fluorobenzoate ligands and two water molecules in a distorted N2O4 octahedral geometry. The dihedral angle between the carboxylate group and the adjacent benzene ring is 8.95 (8)°, while the pyridine ring and the benzene ring are oriented at a dihedral angle of 75.01 (7)°. The water molecule links the adjacent carboxylate O atom via an intramolecular O—H⋯O hydrogen bond. In the crystal, O—H⋯O, N—H⋯O, C—H⋯O and C—H⋯F hydrogen bonds link the molecules into a three-dimensional network. π–π stacking between parallel pyridine rings [centroid–centroid distance = 3.7287 (11) Å] is also observed.
