Os Rh Rh Au
OsRh2Au is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two OsRh2Au clusters. Os(1) is bonded in a 3-coordinate geometry to two equivalent Rh(1) and one Au(1) atom. Both Os(1)-Rh(1) bond lengths are 0.23 Å. The Os(1)-Au(1) bond length is 0.20 Å. Rh(1) is bonded in a 3-coordinate geometry to one Os(1), one Rh(1), and one Au(1) atom. The Rh(1)-Rh(1) bond length is 0.20 Å. The Rh(1)-Au(1) bond length is 0.23 Å. Au(1) is bonded in a 3-coordinate geometry to one Os(1) and two equivalent Rh(1) atoms.
