LiMnO2 is High Pressure (4-7GPa) Tellurium-derived structured and crystallizes in the orthorhombic Pnma space group. Li(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form LiO6 octahedra that share corners with four equivalent Li(1)O6 octahedra, corners with five equivalent Mn(1)O6 octahedra, edges with four equivalent Li(1)O6 octahedra, edges with five equivalent Mn(1)O6 octahedra, and  a faceface with one Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 3-47°. Mn(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form distorted MnO6 octahedra that share corners with four equivalent Mn(1)O6 octahedra, corners with five equivalent Li(1)O6 octahedra, edges with four equivalent Mn(1)O6 octahedra, edges with five equivalent Li(1)O6 octahedra, and  a faceface with one Li(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 3-49°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to three equivalent Li(1) and three equivalent Mn(1) atoms. In the second O site, O(2) is bonded to three equivalent Li(1) and three equivalent Mn(1) atoms to form edge-sharing OLi3Mn3 octahedra.
