Abstract: The preparation and structures of caesium lithium sulfate, Cs_1.15Li_2.85(SO₄)₂, and caesium lithium rubidium sulfate, Cs_0.90Li_2.88Rb_0.22(SO₄)₂, are described and discussed in the context of simple and double sulfate polymorphism. The latter structure is related to the former through the substitution of Rb for Cs. In both crystals, the sulfate ions occupy two non-equivalent sites, but the ions are disordered in Cs_1.15Li_2.85(SO₄)₂.

Formula: Cs_1.15Li_2.85(SO₄)₂ and Cs_0.90Li_2.88Rb_0.22(SO₄)₂
