Tc2GeCl is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Tc2GeCl clusters. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a single-bond geometry to one Ge(1) atom. The Tc(1)-Ge(1) bond length is 0.50 Å. In the second Tc site, Tc(2) is bonded in a distorted linear geometry to one Ge(1) and one Cl(1) atom. The Tc(2)-Ge(1) bond length is 0.50 Å. The Tc(2)-Cl(1) bond length is 0.12 Å. Ge(1) is bonded in a linear geometry to one Tc(1) and one Tc(2) atom. Cl(1) is bonded in a single-bond geometry to one Tc(2) atom.
