LiMnF3 crystallizes in the orthorhombic Pnma space group. Li(1) is bonded in a rectangular see-saw-like geometry to two equivalent F(1) and two equivalent F(2) atoms. Mn(1) is bonded to two equivalent F(2) and four equivalent F(1) atoms to form corner-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles range from 12-31°. There are two inequivalent F sites. In the first F site, F(1) is bonded in a T-shaped geometry to one Li(1) and two equivalent Mn(1) atoms. In the second F site, F(2) is bonded in a see-saw-like geometry to two equivalent Li(1) and two equivalent Mn(1) atoms.
LiMnF3 crystallizes in the orthorhombic Pnma space group. Li(1) is bonded in a rectangular see-saw-like geometry to two equivalent F(1) and two equivalent F(2) atoms. Both Li(1)-F(1) bond lengths are 1.91 Å. There is one shorter (1.98 Å) and one longer (1.99 Å) Li(1)-F(2) bond length. Mn(1) is bonded to two equivalent F(2) and four equivalent F(1) atoms to form corner-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles range from 12-31°. Both Mn(1)-F(2) bond lengths are 2.20 Å. There are two shorter (2.12 Å) and two longer (2.14 Å) Mn(1)-F(1) bond lengths. There are two inequivalent F sites. In the first F site, F(1) is bonded in a T-shaped geometry to one Li(1) and two equivalent Mn(1) atoms. In the second F site, F(2) is bonded in a see-saw-like geometry to two equivalent Li(1) and two equivalent Mn(1) atoms.
