Abstract
The structure of the cubic phase of langbeinite-type Tl2Cd2(SO4)(3) at 295 K has been refined from X-ray diffraction data. The bond-valence sums for the monovalent cations show anomalously low values, indicatin g that some Tl atoms are very loosely bonded. The possible relevance o f this result in the phase-transition scheme of compounds similar to T l2Cd2(SO4)(3) is discussed.
