Two novel isopropylamine-templated uranyl chromates, [(CH 3) 2CHNH 3] 3[(UO 2) 3(CrO 4) 2O(OH) 3] (1) and [(CH 3) 2CHNH 3] 2[(UO 2) 2(CrO 4) 3(H 2O)] (2) were prepared by hydrothermal method at 100 °C. The compounds were characterized by electron microprobe analysis and X-ray diffraction crystal structure analysis [1: trigonal, P31m, a = 9.646(4), c = 8.469(4) Å, V = 682.4(5) Å 3; 2: monoclinic, P2 1/c, a = 11.309(3), b = 11.465(3), c = 17.055(5) Å, β = 99.150(6)°, V = 2183.2(11) Å 3]. The structure of 1 is based upon trimers of uranyl bipyramids interlinked by CrO 4 tetrahedra to form [(UO 2) 3(CrO 4) 2O(OH) 3] 3- layers, whereas, in the structure of 2, UO 7 and UO 6(H 2O) pentagonal bipyramids are linked through CrO 4 tetrahedra into the [(UO 2) 2(CrO 4) 3(H 2O)] 2- layers. The structures show many similarities to related uranyl selenate compounds, thus providing additional data on similarities and differences between uranyl sulfates, chromates, selenates, and molybdates.
