TlSnGe2 crystallizes in the triclinic P1 space group. Tl(1) is bonded in a 2-coordinate geometry to one Sn(1), one Ge(2), and two equivalent Ge(1) atoms. The Tl(1)-Sn(1) bond length is 1.74 Å. The Tl(1)-Ge(2) bond length is 2.27 Å. There is one shorter (2.78 Å) and one longer (3.28 Å) Tl(1)-Ge(1) bond length. Sn(1) is bonded in a 1-coordinate geometry to one Tl(1) and two equivalent Ge(1) atoms. There is one shorter (2.27 Å) and one longer (2.86 Å) Sn(1)-Ge(1) bond length. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 6-coordinate geometry to two equivalent Tl(1), two equivalent Sn(1), and two equivalent Ge(2) atoms. There is one shorter (2.41 Å) and one longer (3.13 Å) Ge(1)-Ge(2) bond length. In the second Ge site, Ge(2) is bonded in a 1-coordinate geometry to one Tl(1) and two equivalent Ge(1) atoms.
