Ba Al Rh Rh
BaRh2Al crystallizes in the monoclinic Cm space group. Ba(1) is bonded in a single-bond geometry to four equivalent Rh(2) and one Al(1) atom. There are a spread of Ba(1)-Rh(2) bond distances ranging from 3.34-3.91 Å. The Ba(1)-Al(1) bond length is 1.82 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 5-coordinate geometry to one Rh(2) and four equivalent Al(1) atoms. The Rh(1)-Rh(2) bond length is 1.89 Å. There are a spread of Rh(1)-Al(1) bond distances ranging from 2.06-2.89 Å. In the second Rh site, Rh(2) is bonded in a 9-coordinate geometry to four equivalent Ba(1), one Rh(1), and four equivalent Rh(2) atoms. All Rh(2)-Rh(2) bond lengths are 3.20 Å. Al(1) is bonded in a 5-coordinate geometry to one Ba(1) and four equivalent Rh(1) atoms.
