Tl Sn Sn Rh
RhTlSn2 crystallizes in the monoclinic Cm space group. Rh(1) is bonded in a 4-coordinate geometry to one Tl(1) and three equivalent Sn(2) atoms. The Rh(1)-Tl(1) bond length is 2.46 Å. There is one shorter (1.63 Å) and two longer (2.47 Å) Rh(1)-Sn(2) bond lengths. Tl(1) is bonded in a distorted single-bond geometry to one Rh(1) and one Sn(1) atom. The Tl(1)-Sn(1) bond length is 3.18 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 6-coordinate geometry to one Tl(1), one Sn(2), and four equivalent Sn(1) atoms. The Sn(1)-Sn(2) bond length is 3.08 Å. All Sn(1)-Sn(1) bond lengths are 3.31 Å. In the second Sn site, Sn(2) is bonded in a 1-coordinate geometry to three equivalent Rh(1) and one Sn(1) atom.
