Özet

The title complex, [Co(C6H6N2O)(2)(H2O)(4)](C7H4FO2)(2), contains one Co(II) atom (site symmetry (1) over bar), two monodentate nicotinamide (NA) ligands, four coordinated water molecules and two 2-fluorobenzoate (FB) anions. The four O atoms in the equatorial plane around the Co atom form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by the two N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl group and the adjacent benzene ring is 29.8 (3)degrees, while the pyridine and benzene rings are oriented at a dihedral angle of 7.97 (12)degrees. In the crystal structure, molecules are linked by O-H center dot center dot center dot O, N-H center dot center dot center dot O and N-H center dot center dot center dot F hydrogen bonds, forming an infinite three-dimensional network. pi-pi Contacts between the pyridine and benzene rings [centroid-centroid distance = 3.673 (3) angstrom] may further stabilize the crystal structure.
