LiMnF3 crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded to one F(2), one F(3), and two equivalent F(1) atoms to form corner-sharing LiF4 tetrahedra. Mn(1) is bonded in a 6-coordinate geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. There are three 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 distorted corner-sharing FLi2Mn2 trigonal pyramids. In the second F site, F(2) is bonded in a trigonal planar geometry to one Li(1) and two equivalent Mn(1) atoms. In the third F site, F(3) is bonded in a trigonal non-coplanar geometry to one Li(1) and two equivalent Mn(1) atoms.
LiMnF3 crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded to one F(2), one F(3), and two equivalent F(1) atoms to form corner-sharing LiF4 tetrahedra.
