Pd Pd Rh Rh Rh Rh
Rh2Pd crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two Rh2Pd clusters. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a single-bond geometry to one Rh(2) atom. The Rh(1)-Rh(2) bond length is 0.26 Å. In the second Rh site, Rh(2) is bonded in a distorted bent 150 degrees geometry to one Rh(1) and one Pd(1) atom. The Rh(2)-Pd(1) bond length is 1.38 Å. Pd(1) is bonded in a single-bond geometry to one Rh(2) atom.
