MgTe6O13, magnesium hexatellurate(IV), is isotypic with the structures of divalent first-row transition metal analogues MTe6O13 (M = Mn, Fe, Co, Ni and Zn). The asymmetric unit contains one Mg, two Te and five O atoms of which the Mg and one O atom lie on a threefold rotation axis. The structure is made up from slightly distorted [MgO6] octahedra (isolated from each other), distorted [TeO4] bisphenoids and [TeO4 + 1] tetragonal pyramids sharing corners and edges. This arrangement leads to the formation of a dense three-dimensional structure.
The title compound is isotypic with its Co, Mn, Ni (Irvine et al., 2003), Fe (van der Lee & Astier, 2007; van der Lee, 2013) and Zn (Nawash et al., 2007) analogues. For other phases in the system Mg-Te-O, see: Trömel & Ziethen-Reichnach (1970). For structure determinations of MgTe2O5 and Mg2Te3O8, see: Weil (2005) and Lin et al. (2013), respectively. The crystal chemistry of oxotellurates(IV) has been reviewed by Zemann (1971).
