The crystal structure and photocatalytic properties of a one-dimensional Zinc(II) coordination complex.

Abstract [Zn(CPDC) (NO 3) 2 ] coordination complex (CP1) was synthesized using 1,2-cyclopentanedicarboxylic acid (CPDC) with Zn(NO 3) 2 ·6H 2 O by solution solvothermal method. The crystal structure of CP1 was characterized by power X-ray diffractograms, thermogravimetric analysis, Fourier transform infrared Spectroscopy, UV spectrophotometer and fluorescence photometer. On the basis of UV–visible and fluorescence spectroscopy, the strong absorption and photoluminescence properties were found in visible wavelength region. Furthermore, photocatalytic experiments indicated that the coordination complex might possess relatively well-done photocatalytic property and recycling stability towards the degradation of rhodamine B in aqueous solution under visible light irradiation. These results indicated that the prepared CP1 might work as a potential photocatalyst for treating the organic pollutants efficiently.
