YReFeIr crystallizes in the trigonal R3m space group. Y(1) is bonded in a distorted linear geometry to three equivalent Re(1), one Fe(1), and one Ir(1) atom. All Y(1)-Re(1) bond lengths are 2.71 Å. The Y(1)-Fe(1) bond length is 2.15 Å. The Y(1)-Ir(1) bond length is 2.27 Å. Re(1) is bonded in a 7-coordinate geometry to three equivalent Y(1), one Fe(1), and three equivalent Ir(1) atoms. The Re(1)-Fe(1) bond length is 2.27 Å. All Re(1)-Ir(1) bond lengths are 2.71 Å. Fe(1) is bonded in a 1-coordinate geometry to one Y(1) and one Re(1) atom. Ir(1) is bonded in a distorted single-bond geometry to one Y(1) and three equivalent Re(1) atoms.
