CdTl2Ge crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CdTl2Ge cluster. Cd(1) is bonded in a single-bond geometry to one Tl(1) atom. The Cd(1)-Tl(1) bond length is 0.66 Å. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a distorted single-bond geometry to one Cd(1) and one Tl(2) atom. The Tl(1)-Tl(2) bond length is 1.43 Å. In the second Tl site, Tl(2) is bonded in a distorted bent 120 degrees geometry to one Tl(1) and one Ge(1) atom. The Tl(2)-Ge(1) bond length is 2.10 Å. Ge(1) is bonded in a single-bond geometry to one Tl(2) atom.
