| Abstract: | Cu2(UO2)4(suc)4(pac)4] (1), (Cu(H2O)2)(4,4′-bipy)2](UO2)2(H2O)2(Hca)2]·3H2O (2), and (Cu(H2O)2)(UO2)(bta)]·4H2O (3) were synthesized by the reaction of succinic acid and 3-pyridinecarboxylic acid, citric acid and 4,4′-bipyridine, or 1,2,4,5-benzenetetracarboxylic acid ligands with Cu(NO3)2·3H2O and UO2(CH3COO)2·2H2O. The complexes were characterized by IR and UV–vis spectroscopy, powder X-ray diffraction, single-crystal X-ray diffraction, and photoluminescence spectroscopy. Photocatalytic activities of the complexes were also investigated. |
