Na Na Os Rh
Na2OsRh is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Na2OsRh clusters. Na(1) is bonded in a 2-coordinate geometry to one Os(1) and one Rh(1) atom. The Na(1)-Os(1) bond length is 1.55 Å. The Na(1)-Rh(1) bond length is 1.55 Å. Os(1) is bonded in a 2-coordinate geometry to two equivalent Na(1) atoms. Rh(1) is bonded in a 2-coordinate geometry to two equivalent Na(1) atoms.
