Two new chromates of hexavalent uranium, [C3H10N][(UO2)(CrO4)(NO3)] (1) and [C2H8N]2[(UO2)2· (CrO4)2(Cr2O7)](H2O)2 (2), were prepared by a combination of hydrothermal synthesis and isothermal evaporation. Compounds 1 and 2 crystallize in the triclinic system, space group Р1¯; a = 7.245(3), b = 7.329(3), c = 11.359(4) Å; α = 85.549(6)°, β = 82.547(6)°, γ = 80.174(6)° for 1; a = 7.2063(4), b = 11.5107(7), c = 16.0980(11) Å; α = 70.736(4)°, β = 80.246(4)°, γ = 71.759(4)° for 2. The structures were solved by the direct methods and refined to R1 = 0.064 [for 1495 reflections with Fo > 4σ(Fo)] and 0.047 [for 4529 reflections with Fo > 4σ(Fo)] for 1 and 2, respectively. The crystal structure of 1 is based on [(UO2)(CrO4)(NO3)]– chains between which the isopropylamine molecules are arranged. In the structure of 2, the amine and H2O molecules are localized between the [(UO2)2(CrO4)2(Cr2O7)]2– layers.
