LiMnF4 is Hydrophilite-derived structured and crystallizes in the tetragonal I4_1/a space group. Li(1) is bonded to one F(1), one F(4), two equivalent F(2), and two equivalent F(3) atoms to form LiF6 octahedra that share corners with four equivalent Li(1)F6 octahedra, corners with four equivalent Mn(1)F6 octahedra, and edges with two equivalent Mn(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 42-58°. Mn(1) is bonded to one F(2), one F(3), two equivalent F(1), and two equivalent F(4) atoms to form MnF6 octahedra that share corners with four equivalent Li(1)F6 octahedra, corners with four equivalent Mn(1)F6 octahedra, and edges with two equivalent Li(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 42-58°. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal planar geometry to one Li(1) and two equivalent Mn(1) atoms. In the second F site, F(3) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one Mn(1) atom. In the third F site, F(2) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one Mn(1) atom. In the fourth F site, F(4) is bonded in a distorted trigonal planar geometry to one Li(1) and two equivalent Mn(1) atoms.
