The material described by LiMnO4 crystallizes in the orthorhombic Cmcm space group. Li(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form LiO6 octahedra that share corners with six equivalent Mn(1)O4 tetrahedra and edges with two equivalent Li(1)O6 octahedra. Mn(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form MnO4 tetrahedra that share corners with six equivalent Li(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-52°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Li(1) and one Mn(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one Mn(1) atom. is represented by the CIF file [CIF]
