By using 1, 2, 4, 5-benzenetetracarboxylic acid as organic ligands, two uranyl coordination complexes, (UO2)(2)(bta)(DMA)(2) (1) and [(UO2)(2)(bta)(mu(3)-OH2)]center dot 2[HN(CH3)(2)]center dot H2O (2) (H(4)bta = 1, 2, 4, 5-benzenetetracarboxylic acid, DMA = N,N-Dimethylacetamide) were synthesized. The X-ray single crystal analysis revealed that complex 1 exhibits a 3-demensional framework, while complex 2 exhibits a 2-demensional framework. In order to furthermore characterize the two complexes and extend their functional properties, spectroscopies of IR, UV-vis, photoluminescence and surface photovoltage were also studied primarily. In addition, thermogravimetric analyses and photocatalytic studies for complexes I and 2 were discussed in detail. (C) 2013 Elsevier B.V. All rights reserved.
