Tc Tc Tc Tc Sn Rh
Tc4RhSn crystallizes in the trigonal R3m space group. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 5-coordinate geometry to one Tc(2), two equivalent Tc(1), one Rh(1), and one Sn(1) atom. The Tc(1)-Tc(2) bond length is 1.39 Å. Both Tc(1)-Tc(1) bond lengths are 0.80 Å. The Tc(1)-Rh(1) bond length is 2.52 Å. The Tc(1)-Sn(1) bond length is 1.94 Å. In the second Tc site, Tc(2) is bonded in a 6-coordinate geometry to three equivalent Tc(1) and three equivalent Sn(1) atoms. All Tc(2)-Sn(1) bond lengths are 3.15 Å. Rh(1) is bonded in a trigonal pyramidal geometry to three equivalent Tc(1) and one Sn(1) atom. The Rh(1)-Sn(1) bond length is 2.22 Å. Sn(1) is bonded in a distorted single-bond geometry to three equivalent Tc(1), three equivalent Tc(2), and one Rh(1) atom.
