K Be Rh Rh
KBeRh2 crystallizes in the trigonal R3m space group. K(1) is bonded in a 2-coordinate geometry to one Be(1), one Rh(2), and three equivalent Rh(1) atoms. The K(1)-Be(1) bond length is 2.11 Å. The K(1)-Rh(2) bond length is 2.29 Å. All K(1)-Rh(1) bond lengths are 2.71 Å. Be(1) is bonded in a 2-coordinate geometry to one K(1) and one Rh(1) atom. The Be(1)-Rh(1) bond length is 2.29 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 4-coordinate geometry to three equivalent K(1) and one Be(1) atom. In the second Rh site, Rh(2) is bonded in a distorted single-bond geometry to one K(1) atom.
