LiMnF4 is Hydrophilite-derived structured and crystallizes in the orthorhombic Pmmn space group. Li(1) is bonded to two equivalent F(2) and four equivalent F(1) atoms to form LiF6 octahedra that share corners with eight equivalent Mn(1)F6 octahedra and edges with two equivalent Li(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 49-52°. Mn(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form MnF6 octahedra that share corners with eight equivalent Li(1)F6 octahedra and edges with two equivalent Mn(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 49-52°. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one Mn(1) atom. In the second F site, F(2) is bonded in a trigonal planar geometry to one Li(1) and two equivalent Mn(1) atoms.
