Fe Fe Os Rh
OsFe2Rh crystallizes in the monoclinic Cm space group. Os(1) is bonded in a 2-coordinate geometry to one Fe(1), four equivalent Fe(2), and one Rh(1) atom. The Os(1)-Fe(1) bond length is 1.69 Å. There are a spread of Os(1)-Fe(2) bond distances ranging from 2.63-3.33 Å. The Os(1)-Rh(1) bond length is 1.45 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 2-coordinate geometry to one Os(1), one Fe(2), and one Rh(1) atom. The Fe(1)-Fe(2) bond length is 3.36 Å. The Fe(1)-Rh(1) bond length is 1.84 Å. In the second Fe site, Fe(2) is bonded in a 10-coordinate geometry to four equivalent Os(1), one Fe(1), four equivalent Fe(2), and one Rh(1) atom. All Fe(2)-Fe(2) bond lengths are 2.72 Å. The Fe(2)-Rh(1) bond length is 2.71 Å. Rh(1) is bonded in a 2-coordinate geometry to one Os(1), one Fe(1), and one Fe(2) atom.
