Two uranium(IV) sulfate framework compounds were crystallized at room temperature from aqueous solutions containing uranyl ions by photochemical reduction in the presence of 2-propanol. U3H2(SO4)(7)(H2O)(5)center dot 3H(2)O (1) crystallizes in space group P6(5) with a = 9.3052(17) angstrom, c = 53.515(10) angstrom, V = 4012.9(13) angstrom(3), and Z = 6, and U-3(UO2)O-2(SO4)(6)(OH)(0.4)center dot 2.3H(2)O (2) is tetragonal, with space group P4(2)/nmc, a = 25.624(3) angstrom, c = 8.9435(10) angstrom, V = 5872.2(11) angstrom(3), and Z = 8. The structures of 1 and 2 are the most complex among uranium(IV) sulfates.
