Mo Mo Rh Au
Mo2RhAu is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Mo2RhAu clusters. Mo(1) is bonded in a 3-coordinate geometry to one Mo(1), one Rh(1), and one Au(1) atom. The Mo(1)-Mo(1) bond length is 0.33 Å. The Mo(1)-Rh(1) bond length is 0.39 Å. The Mo(1)-Au(1) bond length is 0.39 Å. Rh(1) is bonded in a 3-coordinate geometry to two equivalent Mo(1) and one Au(1) atom. The Rh(1)-Au(1) bond length is 0.33 Å. Au(1) is bonded in a 3-coordinate geometry to two equivalent Mo(1) and one Rh(1) atom.
