Single crystals of SnTeO in the millimetre range grown by chemical vapor transport reactions.

Tin(IV) trioxidotellurate(IV), SnTeO, is a member of the isotypic Te O ( = Ti, Zr, Hf, Sn) series crystallizing with eight formula units per unit cell in space group . In comparison with the previous crystal structure model of SnTeO based on powder X-ray diffraction data [Meunier & Galy (1971 ▸). B, 602-608], the current model based on single-crystal X-ray data is improved in terms of precision and accuracy. Nearly regular [SnO] octa-hedra (Sn site symmetry ..) are situated in the voids of an oxidotellurate(IV) framework built up by corner-sharing [TeO] bis-phenoids (Te site symmetry 2..). A qu-anti-tative structural comparison revealed a very high degree of similarity for the structures with = Ti, Zr, Sn in the TeO series.
