RhPd2Sn is Copper structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three RhPd2Sn clusters. Rh(1) is bonded in a distorted linear geometry to one Pd(1) and one Sn(1) atom. The Rh(1)-Pd(1) bond length is 2.07 Å. The Rh(1)-Sn(1) bond length is 2.42 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 1-coordinate geometry to one Rh(1) atom. In the second Pd site, Pd(2) is bonded in a distorted single-bond geometry to one Sn(1) atom. The Pd(2)-Sn(1) bond length is 2.07 Å. Sn(1) is bonded in a 2-coordinate geometry to one Rh(1) and one Pd(2) atom.
