As Rh Rh Au
Rh2AuAs crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Rh2AuAs clusters. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a distorted linear geometry to one Au(1) and one As(1) atom. The Rh(1)-Au(1) bond length is 2.39 Å. The Rh(1)-As(1) bond length is 1.66 Å. In the second Rh site, Rh(2) is bonded in a single-bond geometry to one As(1) atom. The Rh(2)-As(1) bond length is 1.41 Å. Au(1) is bonded in a single-bond geometry to one Rh(1) atom. As(1) is bonded in a linear geometry to one Rh(1) and one Rh(2) atom.
