Be2IrRh crystallizes in the triclinic P1 space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a 1-coordinate geometry to three equivalent Ir(1) and one Rh(1) atom. There is one shorter (1.61 Å) and two longer (2.45 Å) Be(1)-Ir(1) bond lengths. The Be(1)-Rh(1) bond length is 1.34 Å. In the second Be site, Be(2) is bonded in a single-bond geometry to one Ir(1) and one Rh(1) atom. The Be(2)-Ir(1) bond length is 2.82 Å. The Be(2)-Rh(1) bond length is 0.89 Å. Ir(1) is bonded in a 5-coordinate geometry to one Be(2), three equivalent Be(1), and one Rh(1) atom. The Ir(1)-Rh(1) bond length is 1.34 Å. Rh(1) is bonded in a 3-coordinate geometry to one Be(1), one Be(2), and one Ir(1) atom.
