Fe Bi Ir Pd
FeIrPdBi crystallizes in the trigonal R3m space group. Fe(1) is bonded in a 2-coordinate geometry to three equivalent Ir(1), one Pd(1), and one Bi(1) atom. All Fe(1)-Ir(1) bond lengths are 2.71 Å. The Fe(1)-Pd(1) bond length is 2.25 Å. The Fe(1)-Bi(1) bond length is 2.17 Å. Ir(1) is bonded in a 10-coordinate geometry to three equivalent Fe(1), three equivalent Pd(1), and four equivalent Bi(1) atoms. All Ir(1)-Pd(1) bond lengths are 2.71 Å. There is one shorter (2.25 Å) and three longer (2.99 Å) Ir(1)-Bi(1) bond lengths. Pd(1) is bonded in a distorted single-bond geometry to one Fe(1) and three equivalent Ir(1) atoms. Bi(1) is bonded in a 2-coordinate geometry to one Fe(1) and four equivalent Ir(1) atoms.
