TmRhSn crystallizes in the hexagonal P-62m space group. Tm(1) is bonded in a 11-coordinate geometry to one Rh(2), four equivalent Rh(1), and six equivalent Sn(1) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded in a 9-coordinate geometry to three equivalent Tm(1) and six equivalent Sn(1) atoms. In the second Rh site, Rh(1) is bonded in a 9-coordinate geometry to six equivalent Tm(1) and three equivalent Sn(1) atoms. Sn(1) is bonded in a 10-coordinate geometry to six equivalent Tm(1), two equivalent Rh(1), and two equivalent Rh(2) atoms.
TmRhSn crystallizes in the hexagonal P-62m space group. Tm(1) is bonded in a 11-coordinate geometry to one Rh(2), four equivalent Rh(1), and six equivalent Sn(1) atoms. The Tm(1)-Rh(2) bond length is 3.04 Å. All Tm(1)-Rh(1) bond lengths are 2.95 Å. There are two shorter (3.11 Å) and four longer (3.26 Å) Tm(1)-Sn(1) bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded in a 9-coordinate geometry to three equivalent Tm(1) and six equivalent Sn(1) atoms. All Rh(2)-Sn(1) bond lengths are 2.73 Å. In the second Rh site, Rh(1) is bonded in a 9-coordinate geometry to six equivalent Tm(1) and three equivalent Sn(1) atoms. All Rh(1)-Sn(1) bond lengths are 2.80 Å. Sn(1) is bonded in a 10-coordinate geometry to six equivalent Tm(1), two equivalent Rh(1), and two equivalent Rh(2) atoms.
