KBeRh2 crystallizes in the monoclinic Cm space group. K(1) is bonded in a single-bond geometry to one Be(1) and four equivalent Rh(2) atoms. The K(1)-Be(1) bond length is 0.41 Å. There are a spread of K(1)-Rh(2) bond distances ranging from 2.89-3.30 Å. Be(1) is bonded in a single-bond geometry to one K(1) and three equivalent Rh(1) atoms. There is one shorter (2.57 Å) and two longer (2.80 Å) Be(1)-Rh(1) bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 3-coordinate geometry to three equivalent Be(1) and one Rh(2) atom. The Rh(1)-Rh(2) bond length is 3.42 Å. In the second Rh site, Rh(2) is bonded in a 9-coordinate geometry to four equivalent K(1), one Rh(1), and four equivalent Rh(2) atoms. All Rh(2)-Rh(2) bond lengths are 2.85 Å.
