The Synthesis, Characterization and Structural Analysis of a Co(III) Complex of 1,10-phenanthroline and Perfluorosebacic Acid, [Co(HL)(phen)2(H2O)]L • H2O

Abstract

The hexacoordinated mononuclear Co(III) complex 1, [Co(HL)(phen)(2)(H2O)]L center dot H2O, with the mixed ligands (H2L = HO2C(CF2)(8)CO2H and 1,10-phenantroline) has been synthesized and characterized by elemental analysis, IR and UV/vis spectroscopy, magnetic susceptibility, TG analysis and X-ray diffraction techniques. The Co(III) atom is coordinated asymmetrically by two bidentate 1,10 phenanthroline ligands, one hydrogencarboxylate ligand, (O2C(CF2)(8)CO2H)(-), and one water molecule. In the crystal structure, there are also dicarboxylate anions and one water molecule attached through hydrogen bonds. Intermolecular pi-pi interactions between the adjacent phenanthroline ligands also support the packing of the components.
