LiMnO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Li(1) is bonded to six equivalent O(1) atoms to form LiO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra, edges with six equivalent Li(1)O6 octahedra, and edges with six equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 5°. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Li(1)O6 octahedra, edges with six equivalent Li(1)O6 octahedra, and edges with six equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 5°. O(1) is bonded to three equivalent Li(1) and three equivalent Mn(1) atoms to form a mixture of edge and corner-sharing OLi3Mn3 octahedra. The corner-sharing octahedra are not tilted.
