TcGe5 crystallizes in the triclinic P1 space group. Tc(1) is bonded in a single-bond geometry to one Ge(1), one Ge(2), and two equivalent Ge(4) atoms. The Tc(1)-Ge(1) bond length is 2.55 Å. The Tc(1)-Ge(2) bond length is 0.37 Å. There is one shorter (2.45 Å) and one longer (3.28 Å) Tc(1)-Ge(4) bond length. There are five inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 3-coordinate geometry to one Tc(1), one Ge(2), and one Ge(4) atom. The Ge(1)-Ge(2) bond length is 2.35 Å. The Ge(1)-Ge(4) bond length is 2.53 Å. In the second Ge site, Ge(2) is bonded in a single-bond geometry to one Tc(1), one Ge(1), and one Ge(4) atom. The Ge(2)-Ge(4) bond length is 2.53 Å. In the third Ge site, Ge(3) is bonded in a single-bond geometry to one Ge(5) and two equivalent Ge(4) atoms. The Ge(3)-Ge(5) bond length is 1.00 Å. There is one shorter (2.36 Å) and one longer (2.71 Å) Ge(3)-Ge(4) bond length. In the fourth Ge site, Ge(4) is bonded in a 7-coordinate geometry to two equivalent Tc(1), one Ge(1), one Ge(2), one Ge(5), and two equivalent Ge(3) atoms. The Ge(4)-Ge(5) bond length is 2.04 Å. In the fifth Ge site, Ge(5) is bonded in a distorted single-bond geometry to one Ge(3) and one Ge(4) atom.
