摘要: The crystal structure of the title compound, magnesium pentaoxoditellurate(IV), has been redetermined from a grown melt and confirms previous study [Tromel (1975). Z. Anorg. Allg. Chem. 418, 141–144], but with improved precision. It is isotypic β-MnTe2O5 contains MgO6 octahedra TeO3+1 units, latter forming an extended sheet structure. Mg one O atom occupy special positions site symmetry 2.
