Tl6Cl4S crystallizes in the tetragonal P4/mnc space group. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a distorted single-bond geometry to one S(1) and two equivalent Cl(1) atoms. In the second Tl site, Tl(2) is bonded in a 5-coordinate geometry to one S(1) and four equivalent Cl(1) atoms. S(1) is bonded in an octahedral geometry to two equivalent Tl(2) and four equivalent Tl(1) atoms. Cl(1) is bonded in a 4-coordinate geometry to two equivalent Tl(1) and two equivalent Tl(2) atoms.

In the first Tl site, Tl(1) is bonded in a distorted single-bond geometry to one S(1) and two equivalent Cl(1) atoms. The Tl(1)-S(1) bond length is 2.92 Å. Both Tl(1)-Cl(1) bond lengths are 3.23 Å. In the second Tl site, Tl(2) is bonded in a 5-coordinate geometry to one S(1) and four equivalent Cl(1) atoms. The Tl(2)-S(1) bond length is 2.83 Å. All Tl(2)-Cl(1) bond lengths are 3.19 Å. S(1) is bonded in an octahedral geometry to two equivalent Tl(2) and four equivalent Tl(1) atoms. Cl(1) is bonded in a 4-coordinate geometry to two equivalent Tl(1) and two equivalent Tl(2) atoms.
