Abstract

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)₅·3H₂O (1) crystallizes in space group P6₅ with a = 9.3052(17) Å, c = 53.515(10) Å, V = 4012.9(13) Å³, and Z = 6, and U₃(UO₂)_0.2(SO₄)₆(OH)_0.4·2.3H₂O (2) is tetragonal, with space group P4₂/nmc, a = 25.624(3) Å, c = 8.9435(10) Å, V = 5872.2(11) Å³, and Z = 8. The structures of 1 and 2 are the most complex among uranium(IV) sulfates.
