TcSnGe2 crystallizes in the triclinic P1 space group. Tc(1) is bonded in a distorted single-bond geometry to one Sn(1) and two equivalent Ge(1) atoms. The Tc(1)-Sn(1) bond length is 1.04 Å. There is one shorter (2.49 Å) and one longer (3.16 Å) Tc(1)-Ge(1) bond length. Sn(1) is bonded in a 2-coordinate geometry to one Tc(1), one Ge(2), and two equivalent Ge(1) atoms. The Sn(1)-Ge(2) bond length is 1.66 Å. There is one shorter (2.72 Å) and one longer (2.93 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 Tc(1), two equivalent Sn(1), and two equivalent Ge(2) atoms. There is one shorter (2.50 Å) and one longer (2.83 Å) Ge(1)-Ge(2) bond length. In the second Ge site, Ge(2) is bonded in a distorted single-bond geometry to one Sn(1) and two equivalent Ge(1) atoms.
