SmTc2Rh crystallizes in the trigonal R3m space group. Sm(1) is bonded in a 10-coordinate geometry to three equivalent Tc(1), three equivalent Tc(2), and four equivalent Rh(1) atoms. All Sm(1)-Tc(1) bond lengths are 2.70 Å. All Sm(1)-Tc(2) bond lengths are 2.70 Å. There is one shorter (2.61 Å) and three longer (2.87 Å) Sm(1)-Rh(1) bond lengths. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 7-coordinate geometry to three equivalent Sm(1), one Tc(2), and three equivalent Rh(1) atoms. The Tc(1)-Tc(2) bond length is 2.61 Å. All Tc(1)-Rh(1) bond lengths are 2.70 Å. In the second Tc site, Tc(2) is bonded in a distorted single-bond geometry to three equivalent Sm(1), one Tc(1), and one Rh(1) atom. The Tc(2)-Rh(1) bond length is 1.68 Å. Rh(1) is bonded in a 1-coordinate geometry to four equivalent Sm(1), one Tc(2), and three equivalent Tc(1) atoms.
