ReTc2Cl crystallizes in the monoclinic Cm space group. Re(1) is bonded in a single-bond geometry to one Tc(2) and one Cl(1) atom. The Re(1)-Tc(2) bond length is 2.89 Å. The Re(1)-Cl(1) bond length is 2.54 Å. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a single-bond geometry to one Tc(2) and one Cl(1) atom. The Tc(1)-Tc(2) bond length is 2.84 Å. The Tc(1)-Cl(1) bond length is 0.35 Å. In the second Tc site, Tc(2) is bonded to one Re(1), one Tc(1), and six equivalent Tc(2) atoms to form a mixture of corner and edge-sharing TcReTc7 hexagonal bipyramids. All Tc(2)-Tc(2) bond lengths are 2.85 Å. Cl(1) is bonded in a single-bond geometry to one Re(1) and one Tc(1) atom.
