BeFe4Rh crystallizes in the trigonal R3m space group. Be(1) is bonded in a single-bond geometry to one Rh(1) atom. The Be(1)-Rh(1) bond length is 0.50 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 3-coordinate geometry to two equivalent Fe(1), three equivalent Fe(2), and one Rh(1) atom. Both Fe(1)-Fe(1) bond lengths are 1.61 Å. There are two shorter (2.65 Å) and one longer (2.79 Å) Fe(1)-Fe(2) bond length. The Fe(1)-Rh(1) bond length is 1.84 Å. In the second Fe site, Fe(2) is bonded in a 9-coordinate geometry to nine equivalent Fe(1) atoms. Rh(1) is bonded in a single-bond geometry to one Be(1) and three equivalent Fe(1) atoms.
