Tl(SbCl)2 is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Tl(SbCl)2 clusters. Tl(1) is bonded in a distorted single-bond geometry to one Sb(1) atom. The Tl(1)-Sb(1) bond length is 0.81 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted single-bond geometry to one Tl(1) and two equivalent Cl(1) atoms. Both Sb(1)-Cl(1) bond lengths are 1.98 Å. In the second Sb site, Sb(2) is bonded in a 2-coordinate geometry to two equivalent Cl(1) atoms. Both Sb(2)-Cl(1) bond lengths are 0.43 Å. Cl(1) is bonded in a 3-coordinate geometry to one Sb(1), one Sb(2), and one Cl(1) atom. The Cl(1)-Cl(1) bond length is 0.47 Å.
