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.

Diaqua-bis(2-carboxy-benzoato-?O)nickel(II).

Project description:In the title compound, [Ni(C(8)H(5)O(4))(2)(H(2)O)(2)], the Ni(II) atom lies on an inversion centre and exhibits a square-planar geometry incorporating two phthalate and two water O atoms. The nickel complex is stabilized by intra-molecular inter-actions involving water O atoms and H atoms of the phthalate groups. It forms one-dimensional zigzag chains along the b axis which are held together via ?-? stacking inter-actions (3.647?Å) between the benzene rings of the phthalate groups. The adjacent chains are also hydrogen bonded, resulting in a three-dimensional supra-molecular network.
