Abstract
The title complex, [Co(C6H6N2O)2(H2O)4](C7H4FO2)2, contains one Co(II) atom (site symmetry ), 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)°, while the pyridine and benzene rings are oriented at a dihedral angle of 7.97 (12)°. In the crystal structure, molecules are linked by O—H⋯O, N—H⋯O and N—H⋯F hydrogen bonds, forming an infinite three-dimensional network. π–π Contacts between the pyridine and benzene rings [centroid–centroid distance = 3.673 (3) Å] may further stabilize the crystal structure.
