Two new complexes formed by uranyl ions with succinic acid and 4,4'-dipyridine have been investigated. Interestingly, the uranium(VI) coordination polymers possess two types dioxido unit, a cis-dioxido bond angle with 115.421(2)degrees and a trans-dioxido bond angle with 178.421(2)degrees, respectively. The complexes were characterized by elemental analysis, IR and UV-vis spectroscopy and X-ray crystal diffraction. In addition, the properties of luminescence and photocatalytic analysis were also investigated. The result revealed that the two complexes show different photocatalytic activity in the decomposition of RhB under visible light and UV light irradiation.
