Two new U(VI) compounds templated with organic molecules, [(CH 6N) 3(H 2O)][(CH 6N) 2(C 3H 10N)· (H 2O)][(UO 2) 5(CrO 4) 8(H 2O)] (1) and [(C 6H 10N 3O 3)(H 5O 2) 2(H 2O)][(H 5O 2) 3(H 2O)][(UO 2) 5(SO 4) 8(H 2O)] (2), were prepared by combination of hydrothermal synthesis and isothermal evaporation methods. Compounds 1 and 2 crystallize in the monoclinic system, space group P2 1/n, a = 21.921(5), b = 11.016(2), c = 22.021(5) Å, β = 90.571(5)° for 1 and P 2/c, a = 18.1693(17), b = 10.0732(10), c = 30.098(3) Å, β = 103.427(2)° for 2. The reflections from the single crystals were collected at 100 K. The structures were solved by the direct methods and refined to R 1 = 0.053 and 0.070 for 1 and 2, respectively. The crystal structures of 1 and 2 are based on [(UO 2) 5(TO 4) 8(H 2O)] 6– modular layers (T = S 6+, Cr 6+) between which protonated organic molecules, water molecules, and hydroxonium ions are located. Specific features of the crystal chemistry of U(VI) compounds with tetrahedral oxoanions with the ratio UO 2: TO 4 = 5: 8 (T = S 6+, Cr 6+, Se 6+, Mo 6+) are considered.
