Diaquabis(4-fluorobenzoato-O)bis(nicotinamide-N¹)cobalt(II)

N. Çaylak, T. Hökelek and H. Necefoglu

Abstract: The title Co^II complex, [Co(C₇H₄FO₂)₂(C₆H₆N₂O)₂(H₂O)₂], is monomeric and centrosymmetric. It contains two 4-fluorobenzoate and two nicotinamide ligands and two water molecules, all ligands being monodentate. The four O atoms in the equatorial plane around the Co atom form a slightly distorted square-planar arrangement, while the distorted octahedral coordination is completed by the two N atoms in the axial positions. In the crystal structure, O-HO and N-HO hydrogen bonds link the molecules, to form a two-dimensional network parallel to the (10) plane.
