LiMnF3 is Corundum-derived structured and crystallizes in the orthorhombic Cmcm space group. Li(1) is bonded in a 6-coordinate geometry to two equivalent F(1) and four equivalent F(2) atoms. Mn(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form a mixture of edge and corner-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles are 57°. There are two inequivalent F sites. In the first F site, F(1) is bonded to two equivalent Li(1) and two equivalent Mn(1) atoms to form corner-sharing FLi2Mn2 tetrahedra. In the second F site, F(2) is bonded in a distorted square co-planar geometry to two equivalent Li(1) and two equivalent Mn(1) atoms.
