Na Fe Rh Rh
NaFeRh2 crystallizes in the monoclinic Cm space group. Na(1) is bonded in a single-bond geometry to one Fe(1) and four equivalent Rh(2) atoms. The Na(1)-Fe(1) bond length is 0.82 Å. There are a spread of Na(1)-Rh(2) bond distances ranging from 2.67-3.41 Å. Fe(1) is bonded in a single-bond geometry to one Na(1) and one Rh(1) atom. The Fe(1)-Rh(1) bond length is 3.41 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to one Fe(1), one Rh(2), and four equivalent Rh(1) atoms to form a mixture of distorted edge and corner-sharing RhFeRh5 octahedra. The corner-sharing octahedra are not tilted. The Rh(1)-Rh(2) bond length is 1.91 Å. All Rh(1)-Rh(1) bond lengths are 2.69 Å. In the second Rh site, Rh(2) is bonded in a 9-coordinate geometry to four equivalent Na(1), one Rh(1), and four equivalent Rh(2) atoms. All Rh(2)-Rh(2) bond lengths are 2.69 Å.
