Sn Sn Rh Au
RhAuSn2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RhAuSn2 clusters. Rh(1) is bonded in a 3-coordinate geometry to one Au(1), one Sn(1), and one Sn(2) atom. The Rh(1)-Au(1) bond length is 0.97 Å. The Rh(1)-Sn(1) bond length is 1.07 Å. The Rh(1)-Sn(2) bond length is 1.13 Å. Au(1) is bonded in an L-shaped geometry to one Rh(1) and one Sn(2) atom. The Au(1)-Sn(2) bond length is 0.62 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a single-bond geometry to one Rh(1) atom. In the second Sn site, Sn(2) is bonded in a distorted single-bond geometry to one Rh(1) and one Au(1) atom.
