MnTlF4 crystallizes in the monoclinic C2/c 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 are 37°. Tl(1) is bonded in a 2-coordinate geometry to two equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to one Mn(1) and one Tl(1) atom. In the second F site, F(2) is bonded in a bent 150 degrees geometry to two equivalent Mn(1) atoms.
MnTlF4 crystallizes in the monoclinic C2/c 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 are 37°. Both Mn(1)-F(1) bond lengths are 1.84 Å. There are two shorter (1.87 Å) and two longer (2.13 Å) Mn(1)-F(2) bond lengths. Tl(1) is bonded in a 2-coordinate geometry to two equivalent F(1) atoms. Both Tl(1)-F(1) bond lengths are 2.65 Å. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to one Mn(1) and one Tl(1) atom. In the second F site, F(2) is bonded in a bent 150 degrees geometry to two equivalent Mn(1) atoms.
