Tc Ge Te
TcGeTe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TcGeTe clusters. Tc(1) is bonded in a single-bond geometry to one Ge(1) atom. The Tc(1)-Ge(1) bond length is 1.72 Å. Ge(1) is bonded in a distorted linear geometry to one Tc(1) and one Te(1) atom. The Ge(1)-Te(1) bond length is 0.91 Å. Te(1) is bonded in a single-bond geometry to one Ge(1) atom.
