Si Rh Au Au
AuRhAuSi is beta oxygen-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two gold;rhodium molecules and two AuSi clusters. In each AuSi cluster, Au(2) is bonded in a single-bond geometry to one Si(1) atom. The Au(2)-Si(1) bond length is 1.82 Å. Si(1) is bonded in a single-bond geometry to one Au(2) atom.
