Re Rh Rh Au
ReRh2Au crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ReRh2Au clusters. Re(1) is bonded in a single-bond geometry to one Rh(2) and one Au(1) atom. The Re(1)-Rh(2) bond length is 1.70 Å. The Re(1)-Au(1) bond length is 0.43 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 1-coordinate geometry to one Au(1) atom. The Rh(1)-Au(1) bond length is 1.91 Å. In the second Rh site, Rh(2) is bonded in a 1-coordinate geometry to one Re(1) atom. Au(1) is bonded in a single-bond geometry to one Re(1) and one Rh(1) atom.
