BeCrRh4 crystallizes in the trigonal R3m space group. Be(1) is bonded in a distorted trigonal non-coplanar geometry to one Cr(1), three equivalent Rh(1), and three equivalent Rh(2) atoms. The Be(1)-Cr(1) bond length is 2.81 Å. All Be(1)-Rh(1) bond lengths are 2.49 Å. All Be(1)-Rh(2) bond lengths are 3.12 Å. Cr(1) is bonded in a 10-coordinate geometry to one Be(1), three equivalent Rh(2), and six equivalent Rh(1) atoms. All Cr(1)-Rh(2) bond lengths are 2.89 Å. There are three shorter (2.44 Å) and three longer (2.84 Å) Cr(1)-Rh(1) bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded in a 9-coordinate geometry to three equivalent Be(1), three equivalent Cr(1), and three equivalent Rh(1) atoms. All Rh(2)-Rh(1) bond lengths are 1.95 Å. In the second Rh site, Rh(1) is bonded in a 6-coordinate geometry to one Be(1), two equivalent Cr(1), one Rh(2), and two equivalent Rh(1) atoms. Both Rh(1)-Rh(1) bond lengths are 1.12 Å.
