Tc Tc Ge Rh
Tc2RhGe crystallizes in the triclinic P1 space group. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 3-coordinate geometry to two equivalent Tc(2), one Rh(1), and one Ge(1) atom. There is one shorter (1.17 Å) and one longer (2.25 Å) Tc(1)-Tc(2) bond length. The Tc(1)-Rh(1) bond length is 2.02 Å. The Tc(1)-Ge(1) bond length is 1.65 Å. In the second Tc site, Tc(2) is bonded in a 5-coordinate geometry to two equivalent Tc(1), two equivalent Rh(1), and one Ge(1) atom. There is one shorter (2.17 Å) and one longer (2.42 Å) Tc(2)-Rh(1) bond length. The Tc(2)-Ge(1) bond length is 2.53 Å. Rh(1) is bonded in a 4-coordinate geometry to one Tc(1), two equivalent Tc(2), and one Ge(1) atom. The Rh(1)-Ge(1) bond length is 2.40 Å. Ge(1) is bonded in a 1-coordinate geometry to one Tc(1), one Tc(2), and one Rh(1) atom.
