Tc Tc Cl
Tc2Cl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Tc2Cl cluster. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a distorted single-bond geometry to one Cl(1) atom. The Tc(1)-Cl(1) bond length is 1.62 Å. In the second Tc site, Tc(2) is bonded in a single-bond geometry to one Cl(1) atom. The Tc(2)-Cl(1) bond length is 1.26 Å. Cl(1) is bonded in a 2-coordinate geometry to one Tc(1) and one Tc(2) atom.
