TcB2Ge crystallizes in the triclinic P1 space group. Tc(1) is bonded in a 10-coordinate geometry to four equivalent B(1), four equivalent B(2), and two equivalent Ge(1) atoms. There are a spread of Tc(1)-B(1) bond distances ranging from 2.05-2.31 Å. There are a spread of Tc(1)-B(2) bond distances ranging from 2.05-2.31 Å. There is one shorter (2.59 Å) and one longer (2.60 Å) Tc(1)-Ge(1) bond length. There are two inequivalent B sites. In the first B site, B(1) is bonded in a distorted single-bond geometry to four equivalent Tc(1), one B(2), and two equivalent Ge(1) atoms. The B(1)-B(2) bond length is 1.04 Å. There is one shorter (2.48 Å) and one longer (2.49 Å) B(1)-Ge(1) bond length. In the second B site, B(2) is bonded in a distorted single-bond geometry to four equivalent Tc(1) and one B(1) atom. Ge(1) is bonded in a 4-coordinate geometry to two equivalent Tc(1) and two equivalent B(1) atoms.
