Ni Sn Sn Rh
RhNiSn2 crystallizes in the triclinic P1 space group. Rh(1) is bonded in a single-bond geometry to one Ni(1) and one Sn(2) atom. The Rh(1)-Ni(1) bond length is 1.29 Å. The Rh(1)-Sn(2) bond length is 2.92 Å. Ni(1) is bonded in a distorted single-bond geometry to one Rh(1) and four equivalent Sn(1) atoms. There are a spread of Ni(1)-Sn(1) bond distances ranging from 2.12-2.99 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 5-coordinate geometry to four equivalent Ni(1) and one Sn(2) atom. The Sn(1)-Sn(2) bond length is 1.70 Å. In the second Sn site, Sn(2) is bonded in a 2-coordinate geometry to one Rh(1) and one Sn(1) atom.
