TlGeCl2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TlGeCl2 cluster. Tl(1) is bonded in a distorted single-bond geometry to one Cl(1) and one Cl(2) atom. The Tl(1)-Cl(1) bond length is 2.01 Å. The Tl(1)-Cl(2) bond length is 0.50 Å. Ge(1) is bonded in a 2-coordinate geometry to one Cl(1) and one Cl(2) atom. The Ge(1)-Cl(1) bond length is 2.21 Å. The Ge(1)-Cl(2) bond length is 2.36 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 2-coordinate geometry to one Tl(1) and one Ge(1) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Tl(1) and one Ge(1) atom.
