In the first Te4+ site, Te4+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with two equivalent CrO6 octahedra, an edgeedge with one CrO6 octahedra, edges with two equivalent MnO6 octahedra, and edges with two equivalent TeO6 octahedra. The corner-sharing octahedra tilt angles range from 50–51°. There are a spread of Te–O bond distances ranging from 1.90–2.04 Å. In the second Te4+ site, Te4+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with two equivalent CrO6 octahedra, an edgeedge with one CrO6 octahedra, and edges with four equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of Te–O bond distances ranging from 1.95–2.01 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Cr+4.50+, one Mn+3.67+, and one Te4+ atom. In the second O2- site, O2- is bonded in a distorted T-shaped geometry to one Cr+4.50+ and two equivalent Te4+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Mn+3.67+ and two equivalent Te4+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Mn+3.67+ and two equivalent Te4+ atoms. In the fifth O2- site, O2- is bonded in a trigonal non-coplanar geometry to two equivalent Mn+3.67+ and one Te4+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Cr+4.50+, one Mn+3.67+, and one Te4+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Cr+4.50+ and two equivalent Te4+ atoms. In the eighth O2- site, O2- is bonded in a trigonal planar geometry to one Cr+4.50+ and two equivalent Mn+3.67+ atoms.
