TcHgGe2 crystallizes in the triclinic P1 space group. Tc(1) is bonded in a 4-coordinate geometry to one Hg(1), one Ge(2), and two equivalent Ge(1) atoms. The Tc(1)-Hg(1) bond length is 1.84 Å. The Tc(1)-Ge(2) bond length is 2.33 Å. There is one shorter (1.53 Å) and one longer (2.00 Å) Tc(1)-Ge(1) bond length. Hg(1) is bonded in a distorted single-bond geometry to one Tc(1) and two equivalent Ge(2) atoms. There is one shorter (2.62 Å) and one longer (2.94 Å) Hg(1)-Ge(2) bond length. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 2-coordinate geometry to two equivalent Tc(1) and one Ge(2) atom. The Ge(1)-Ge(2) bond length is 2.23 Å. In the second Ge site, Ge(2) is bonded in a 4-coordinate geometry to one Tc(1), two equivalent Hg(1), and one Ge(1) atom.
