Be V Rh Rh
BeVRh2 crystallizes in the monoclinic Cm space group. Be(1) is bonded to one Rh(2) and four equivalent Rh(1) atoms to form a mixture of distorted corner and edge-sharing BeRh5 square pyramids. The Be(1)-Rh(2) bond length is 1.97 Å. There are a spread of Be(1)-Rh(1) bond distances ranging from 2.10-2.27 Å. V(1) is bonded in a 5-coordinate geometry to one Rh(1) and four equivalent Rh(2) atoms. The V(1)-Rh(1) bond length is 1.88 Å. There are a spread of V(1)-Rh(2) bond distances ranging from 2.44-2.58 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to four equivalent Be(1) and one V(1) atom to form a mixture of distorted corner and edge-sharing RhBe4V square pyramids. In the second Rh site, Rh(2) is bonded in a 5-coordinate geometry to one Be(1) and four equivalent V(1) atoms.
