Title: Materials Data on Mg2Te3O8 by Materials Project

Abstract

Mg2Te3O8 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Mg2+ is bonded to six O2- atoms to form a mixture of distorted corner and edge-sharing MgO6 octahedra. The corner-sharing octahedral tilt angles are 56°. There are a spread of Mg–O bond distances ranging from 2.05–2.30 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a see-saw-like geometry to four O2- atoms. There are two shorter (1.89 Å) and two longer (2.13 Å) Te–O bond lengths. In the second Te4+ site, Te4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Te–O bond distances ranging from 1.90–2.76 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Mg2+ and one Te4+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Mg2+ and two equivalent Te4+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mg2+ and two Te4+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Mg2+more » and two Te4+ atoms.« less
