Dirubidium dicadmium sulfate at 293 K.
The structure of Rb2Cd2(SO4)3 at room temperature has been refined using X-ray diffraction data. The structure is similar to that of other cubic langbeinites. However, the title compound differs from other type I langbeinites in that the bond-valence sums of the metal cations (in particular the Rb atoms) are practically equal to their nominal chemical valences.
