MnF3 crystallizes in the orthorhombic Pnma space group. Mn(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form corner-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles range from 35-36°. There are two inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to two equivalent Mn(1) atoms. In the second F site, F(2) is bonded in a bent 150 degrees geometry to two equivalent Mn(1) atoms.
MnF3 crystallizes in the orthorhombic Pnma space group. Mn(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form corner-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles range from 35-36°. Both Mn(1)-F(1) bond lengths are 1.91 Å. There are two shorter (1.82 Å) and two longer (2.08 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 150 degrees geometry to two equivalent Mn(1) atoms. In the second F site, F(2) is bonded in a bent 150 degrees geometry to two equivalent Mn(1) atoms.
