TcFe2Ge crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TcFe2Ge clusters. Tc(1) is bonded in a 3-coordinate geometry to two equivalent Fe(1) and one Ge(1) atom. Both Tc(1)-Fe(1) bond lengths are 1.23 Å. The Tc(1)-Ge(1) bond length is 1.24 Å. Fe(1) is bonded in a single-bond geometry to one Tc(1) and one Ge(1) atom. The Fe(1)-Ge(1) bond length is 0.55 Å. Ge(1) is bonded in a water-like geometry to one Tc(1) and two equivalent Fe(1) atoms.
