The reaction of 1-(2-pyridylazo)-2-acenaphthequinol (PAAL) with cobalt acetate in CHCl3 gave the complex of Co(PAAL-H)2 (1), and (PAAL + H)2[CoCl4]·2H2O (2) was isolated in the same system with ultraviolet light irradiation. Structures of both compounds were determined by X-Ray diffraction. The PAAL ligand was deprotonated in 1, but it further protonated on N position at pyridine group in 2 and form cations. The spectra of these two compounds were also studied, as well as the fluorescence properties. Also, the redox property of 1 was preliminary investigated by cyclic voltammogram.
