BeRh2Zn crystallizes in the monoclinic Cm space group. Be(1) is bonded in a single-bond geometry to four equivalent Rh(2) and one Zn(1) atom. There are a spread of Be(1)-Rh(2) bond distances ranging from 2.65-3.02 Å. The Be(1)-Zn(1) bond length is 0.08 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 9-coordinate geometry to one Rh(2), four equivalent Rh(1), and four equivalent Zn(1) atoms. The Rh(1)-Rh(2) bond length is 1.92 Å. All Rh(1)-Rh(1) bond lengths are 2.87 Å. There are a spread of Rh(1)-Zn(1) bond distances ranging from 2.71-3.08 Å. In the second Rh site, Rh(2) is bonded in a 9-coordinate geometry to four equivalent Be(1), one Rh(1), and four equivalent Rh(2) atoms. All Rh(2)-Rh(2) bond lengths are 2.87 Å. Zn(1) is bonded in a single-bond geometry to one Be(1) and four equivalent Rh(1) atoms.
