In the fourteenth O site, O(14) is bonded to three equivalent Li(7) and three equivalent Mn(1) atoms to form OLi3Mn3 octahedra that share corners with three equivalent O(7)Li3Co3 octahedra, corners with three equivalent O(1)Li3Mn3 octahedra, edges with three equivalent O(7)Li3Co3 octahedra, edges with three equivalent O(1)Li3Mn3 octahedra, and edges with six equivalent O(14)Li3Mn3 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. is represented by the CIF file [CIF]
