TcSnGe2 crystallizes in the triclinic P1 space group. Tc(1) is bonded in a single-bond geometry to one Sn(1), one Ge(1), and two equivalent Ge(2) atoms. The Tc(1)-Sn(1) bond length is 2.36 Å. The Tc(1)-Ge(1) bond length is 0.58 Å. There is one shorter (2.27 Å) and one longer (2.55 Å) Tc(1)-Ge(2) bond length. Sn(1) is bonded in a 6-coordinate geometry to one Tc(1), two equivalent Sn(1), one Ge(1), and two equivalent Ge(2) atoms. Both Sn(1)-Sn(1) bond lengths are 3.26 Å. The Sn(1)-Ge(1) bond length is 2.68 Å. There is one shorter (2.68 Å) and one longer (2.91 Å) Sn(1)-Ge(2) bond length. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a single-bond geometry to one Tc(1), one Sn(1), and one Ge(2) atom. The Ge(1)-Ge(2) bond length is 2.28 Å. In the second Ge site, Ge(2) is bonded in a 5-coordinate geometry to two equivalent Tc(1), two equivalent Sn(1), and one Ge(1) atom.
