Single crystals of SnTe(3)O(8) in the millimetre range grown by chemical vapor transport reactions

Tin(IV) trioxidotellurate(IV), SnTe(3)O(8), is a member of the isotypic M (IV)Te(IV) (3)O(8) (M = Ti, Zr, Hf, Sn) series crystallizing with eight formula units per unit cell in space group Ia [Image: see text] . In comparison with the previous crystal structure model of SnTe(3)O(8) based on powder X-ray diffraction data [Meunier & Galy (1971 ▸). Acta Cryst. B27, 602–608], the current model based on single-crystal X-ray data is improved in terms of precision and accuracy. Nearly regular [SnO(6)] octa­hedra (Sn site symmetry . [Image: see text] .) are situated in the voids of an oxidotellurate(IV) framework built up by corner-sharing [TeO(4)] bis­phenoids (Te site symmetry 2..). A qu­anti­tative structural comparison revealed a very high degree of similarity for the structures with M = Ti, Zr, Sn in the M (IV)Te(3)O(8) series.
