A new copper-based coordination compound Cu 2 (2,2′-bipy) 2 (pfbz) 4 ( 1 ) (where 2,2′-bipy = 2,2′-bipyridine; pfbz = pentafluorobenzoate), was hydrothermally synthesized and structurally characterized. Compound 1 having a binuclear structure consists of two copper cations and two oxygen atoms alternately in a plane square arrangement. In the presence of very small amounts of H 2 O 2 , the catalytic properties of compound 1 for the degradation of methyl orange (MO) are excellent in the absence of UV-visible radiation. Moreover, compound 1 presents suitable properties for degradation of Congo red (CR). Our results indicated that the five-coordinated copper compound, 1 , will be a promising candidate for efficient degradation of organic dyes. A five-coordinated compound, Cu 2 (2,2-bipy) 2 (pfbz) 4 , displays excellent properties of degrading methyl orange and Congo red in the absence of UV-visible radiation.
