MnTe6O13 crystallizes in the trigonal R-3 space group. Mn(1) is bonded in a distorted octahedral geometry to three equivalent O(1) and three equivalent O(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted rectangular see-saw-like geometry to one O(3), one O(4), and two equivalent O(1) atoms. In the second Te site, Te(2) is bonded in a 5-coordinate geometry to one O(4), two equivalent O(2), and two equivalent O(5) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Mn(1) and two equivalent Te(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Mn(1) and two equivalent Te(2) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to three equivalent Te(1) atoms. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Te(1) and one Te(2) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to two equivalent Te(2) atoms.
