Design, synthesis and structure of uranyl coordination polymers from 2-D layer to 3-D network structure

Solvothermal reaction of uranyl acetate and succinic acid in DMF resulted in formation of three uranyl coordination polymers, [(UO2)(4)((2)-OH)(7)(OH)(6)]2(H2O)(H3O)4NH(2)(CH3)(2) (1), [(UO2)((2)-OH)(OH)(3)]2NH(2)(CH3)(2)] (2), and [(DMF)(2)(UO2)((2)-OH)(4)(UO2))] (3). The products were characterized by elemental analysis, IR spectroscopy, X-ray single crystal, and powder diffraction. Structural analysis shows that 1 is a layer, 2 and 3 are 3-D network structures.
