Description
Summary:The title complex, [Co(C(6)H(6)N(2)O)(2)(H(2)O)(4)](C(7)H(4)FO(2))(2), contains one Co(II) atom (site symmetry ), two monodentate nicotin-amide (NA) ligands, four coordinated water mol-ecules and two 2-fluoro-benzoate (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 octa-hedral 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, mol-ecules 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.
