CrFeRh is alpha boron-derived structured and crystallizes in the trigonal R3m space group. Cr(1) is bonded in a 7-coordinate geometry to three equivalent Fe(1) and four equivalent Rh(1) atoms. All Cr(1)-Fe(1) bond lengths are 2.30 Å. There is one shorter (2.30 Å) and three longer (2.42 Å) Cr(1)-Rh(1) bond lengths. Fe(1) is bonded in a hexagonal planar geometry to three equivalent Cr(1) and three equivalent Rh(1) atoms. All Fe(1)-Rh(1) bond lengths are 2.30 Å. Rh(1) is bonded in a 7-coordinate geometry to four equivalent Cr(1) and three equivalent Fe(1) atoms.
