LiMnF4 crystallizes in the orthorhombic Pnna space group. Li(1) is bonded to two equivalent F(1) and two equivalent F(2) atoms to form distorted LiF4 trigonal pyramids that share corners with six equivalent Mn(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 52-57°. Mn(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form distorted MnF6 octahedra that share corners with six equivalent Li(1)F4 trigonal pyramids and edges with two equivalent Mn(1)F6 octahedra. There are two inequivalent F sites. In the first F site, F(1) is bonded in a bent 120 degrees geometry to one Li(1) and one Mn(1) atom. In the second F site, F(2) is bonded in a distorted trigonal planar geometry to one Li(1) and two equivalent Mn(1) atoms.
LiMnF4 crystallizes in the orthorhombic Pnna space group. Li(1) is bonded to two equivalent F(1) and two equivalent F(2) atoms to form distorted LiF4 trigonal pyramids that share corners with six equivalent Mn(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 52-57°. Both Li(1)-F(1) bond lengths are 1.93 Å. Both Li(1)-F(2) bond lengths are 2.00 Å. Mn(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form distorted MnF6 octahedra that share corners with six equivalent Li(1)F4 trigonal pyramids and edges with two equivalent Mn(1)F6 octahedra. Both Mn(1)-F(1) bond lengths are 1.83 Å. There are two shorter (1.95 Å) and two longer (2.23 Å) Mn(1)-F(2) bond lengths. There are two inequivalent F sites. In the first F site, F(1) is bonded in a bent 120 degrees geometry to one Li(1) and one Mn(1) atom. In the second F site, F(2) is bonded in a distorted trigonal planar geometry to one Li(1) and two equivalent Mn(1) atoms.
