Sr Fe Fe Rh
SrFe2Rh crystallizes in the trigonal R3m space group. Sr(1) is bonded in a 1-coordinate geometry to one Fe(2), three equivalent Fe(1), and three equivalent Rh(1) atoms. The Sr(1)-Fe(2) bond length is 2.09 Å. All Sr(1)-Fe(1) bond lengths are 2.72 Å. All Sr(1)-Rh(1) bond lengths are 2.72 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to three equivalent Sr(1) and one Rh(1) atom to form distorted corner-sharing FeSr3Rh tetrahedra. The Fe(1)-Rh(1) bond length is 2.09 Å. In the second Fe site, Fe(2) is bonded in a distorted linear geometry to one Sr(1) and one Rh(1) atom. The Fe(2)-Rh(1) bond length is 2.39 Å. Rh(1) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Fe(1), and one Fe(2) atom.
