Trans-Diaqua-bis-(4-fluoro-benzoato-?O)bis-(nicotinamide-?N)nickel(II).


ABSTRACT: In the mononuclear Ni(II) title complex, [Ni(C(7)H(4)FO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], the Ni(II) atom, located on an inversion center, is coordinated by two nicotinamide and two 4-fluoro-benzoate ligands and two water mol-ecules in a distorted N(2)O(4) octa-hedral geometry. The dihedral angle between the carboxyl-ate 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 mol-ecule links the adjacent carboxyl-ate O atom via an intra-molecular 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 mol-ecules into a three-dimensional network. ?-? stacking between parallel pyridine rings [centroid-centroid distance = 3.7287?(11)?Å] is also observed.
