HgTlF3 crystallizes in the triclinic P1 space group. Hg(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form distorted corner-sharing HgF6 octahedra. The corner-sharing octahedral tilt angles range from 19-20°. Tl(1) is bonded in a 3-coordinate geometry to one F(1), one F(2), and one F(3) atom. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted T-shaped geometry to two equivalent Hg(1) and one Tl(1) atom. In the second F site, F(2) is bonded in a distorted T-shaped geometry to two equivalent Hg(1) and one Tl(1) atom. In the third F site, F(3) is bonded in a 3-coordinate geometry to two equivalent Hg(1) and one Tl(1) atom.
