Cr Os Os Rh
CrOs2Rh is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CrOs2Rh clusters. Cr(1) is bonded in a 3-coordinate geometry to two equivalent Os(1) and one Rh(1) atom. Both Cr(1)-Os(1) bond lengths are 0.54 Å. The Cr(1)-Rh(1) bond length is 0.52 Å. Os(1) is bonded in a 3-coordinate geometry to one Cr(1), one Os(1), and one Rh(1) atom. The Os(1)-Os(1) bond length is 0.52 Å. The Os(1)-Rh(1) bond length is 0.54 Å. Rh(1) is bonded in a 3-coordinate geometry to one Cr(1) and two equivalent Os(1) atoms.
