Tc2Cl crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two Tc2Cl clusters. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a single-bond geometry to one Cl(1) atom. The Tc(1)-Cl(1) bond length is 0.47 Å. In the second Tc site, Tc(2) is bonded in a distorted single-bond geometry to one Cl(1) atom. The Tc(2)-Cl(1) bond length is 1.98 Å. Cl(1) is bonded in a single-bond geometry to one Tc(1) and one Tc(2) atom.
