The material structure described by Li2MnTiO4 crystallizes in the tetragonal I-4m2 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a rectangular see-saw-like geometry to four O(2,2) atoms. In the second Li site, Li(2) is bonded to two O(2,2) and four equivalent O(1) atoms to form distorted LiO6 octahedra that share corners with two equivalent Mn(1)O6 octahedra, corners with four equivalent Li(2)O6 octahedra, edges with four equivalent Ti(1)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-23°. Ti(1) is bonded to two O(1,1) and four O(2,2) atoms to form TiO6 octahedra that share corners with four equivalent Ti(1)O6 octahedra, edges with four equivalent Li(2)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra.
