The material described by Li4MnNi3O8 is alpha Po-derived structured and crystallizes in the trigonal R-3m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form LiO6 octahedra that share corners with six equivalent Ni(1)O6 octahedra, edges with two equivalent Li(2)O6 octahedra, edges with two equivalent Mn(1)O6 octahedra, edges with four equivalent Li(1)O6 octahedra, and edges with four equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 7-9°. In the second Li site, Li(2) 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 Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles are 1°. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Li(2)O6 octahedra, edges with six equivalent Li(1)O6 octahedra, and edges with six equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles are 1°. Ni(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form NiO6 octahedra that share corners with six equivalent Li(1)O6 octahedra, edges with two equivalent Li(2)O6 octahedra, edges with two equivalent Mn(1)O6 octahedra, edges with four equivalent Li(1)O6 octahedra, and edges with four equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 7-9°. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Li(2), two equivalent Li(1), one Mn(1), and two equivalent Ni(1) atoms to form OLi3MnNi2 octahedra that share corners with six equivalent O(1)Li3MnNi2 octahedra, edges with four equivalent O(2)Li3Ni3 octahedra, and edges with eight equivalent O(1)Li3MnNi2 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded to three equivalent Li(1) and three equivalent Ni(1) atoms to form OLi3Ni3 octahedra that share corners with six equivalent O(2)Li3Ni3 octahedra and edges with twelve equivalent O(1)Li3MnNi2 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
