The structure described by Li2Mn3F8 crystallizes in the cubic P4_332 space group. Li(1) is bonded to one F(2) and three equivalent F(1) atoms to form LiF4 tetrahedra that share corners with nine equivalent Mn(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 53-58°. Mn(1) is bonded to two equivalent F(2) and four equivalent F(1) atoms to form MnF6 octahedra that share corners with six equivalent Li(1)F4 tetrahedra and edges with four equivalent Mn(1)F6 octahedra. There are two inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to one Li(1) and two equivalent Mn(1) atoms. In the second F site, F(2) is bonded to one Li(1) and three equivalent Mn(1) atoms to form distorted corner-sharing FLiMn3 trigonal pyramids. is represented by the CIF file [CIF]
