BeMnRh2 crystallizes in the monoclinic Cm space group. Be(1) is bonded in a linear geometry to one Rh(1) and one Rh(2) atom. The Be(1)-Rh(1) bond length is 0.66 Å. The Be(1)-Rh(2) bond length is 0.27 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to six Mn(1,1); one Rh(1); and one Rh(2) atom to form a mixture of corner and edge-sharing MnMn6Rh2 hexagonal bipyramids. All Mn(1)-Mn(1,1) bond lengths are 2.78 Å. The Mn(1)-Rh(1) bond length is 3.46 Å. The Mn(1)-Rh(2) bond length is 3.46 Å. In the second Mn site, Mn(1) is bonded to six Mn(1,1); one Rh(1); and one Rh(2) atom to form a mixture of corner and edge-sharing MnMn6Rh2 hexagonal bipyramids. Both Mn(1)-Mn(1) bond lengths are 2.78 Å. The Mn(1)-Rh(1) bond length is 3.46 Å. The Mn(1)-Rh(2) bond length is 3.46 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a single-bond geometry to one Be(1) and one Mn(1) atom. In the second Rh site, Rh(2) is bonded in a single-bond geometry to one Be(1) and one Mn(1) atom.
