ReTc2Rh crystallizes in the monoclinic Cm space group. Re(1) is bonded to six equivalent Re(1), one Tc(1), and one Tc(2) atom to form a mixture of distorted corner and edge-sharing ReRe6Tc2 hexagonal bipyramids. All Re(1)-Re(1) bond lengths are 2.74 Å. The Re(1)-Tc(1) bond length is 2.41 Å. The Re(1)-Tc(2) bond length is 2.41 Å. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a single-bond geometry to one Re(1) and one Rh(1) atom. The Tc(1)-Rh(1) bond length is 1.79 Å. In the second Tc site, Tc(2) is bonded in a 1-coordinate geometry to one Re(1) and one Rh(1) atom. The Tc(2)-Rh(1) bond length is 2.50 Å. Rh(1) is bonded in a distorted linear geometry to one Tc(1) and one Tc(2) atom.
