TcZnGe2 crystallizes in the monoclinic Cm space group. Tc(1) is bonded in a single-bond geometry to one Zn(1) and three equivalent Ge(1) atoms. The Tc(1)-Zn(1) bond length is 0.93 Å. There is one shorter (2.62 Å) and two longer (3.19 Å) Tc(1)-Ge(1) bond lengths. Zn(1) is bonded in a 1-coordinate geometry to one Tc(1) and three equivalent Ge(2) atoms. There is one shorter (1.98 Å) and two longer (2.68 Å) Zn(1)-Ge(2) bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 4-coordinate geometry to three equivalent Tc(1) and one Ge(2) atom. The Ge(1)-Ge(2) bond length is 1.56 Å. In the second Ge site, Ge(2) is bonded in a 4-coordinate geometry to three equivalent Zn(1) and one Ge(1) atom.
