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[Irvine, J. T. S., Johnston, M. G. & Harrison, W. T. A. (2003). Dalton Trans. pp. 2641-2645.]), Fe (van der Lee & Astier, 2007[Lee, A. van der & Astier, R. (2007). J. Solid State Chem. 180, 1243-1249.]; van der Lee, 2013[Lee, A. van der (2013). Personal communication.]) and Zn (Nawash et al., 2007[Nawash, J. M., Twamley, B. & Lynn, K. G. (2007). Acta Cryst. C63, i66-i68.]) analogues.
