Al Cd Rh Rh Rh Rh
Rh4CdAl crystallizes in the trigonal R3m space group. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded in a 6-coordinate geometry to three equivalent Rh(1) and three equivalent Cd(1) atoms. All Rh(2)-Rh(1) bond lengths are 1.57 Å. All Rh(2)-Cd(1) bond lengths are 3.09 Å. In the second Rh site, Rh(1) is bonded in a 5-coordinate geometry to one Rh(2), two equivalent Rh(1), one Cd(1), and one Al(1) atom. Both Rh(1)-Rh(1) bond lengths are 0.91 Å. The Rh(1)-Cd(1) bond length is 1.95 Å. The Rh(1)-Al(1) bond length is 2.45 Å. Cd(1) is bonded to three equivalent Rh(1), three equivalent Rh(2), and one Al(1) atom to form distorted CdAlRh6 pentagonal bipyramids that share corners with six equivalent Cd(1)AlRh6 pentagonal bipyramids and corners with three equivalent Al(1)CdRh3 trigonal pyramids. The Cd(1)-Al(1) bond length is 2.25 Å. Al(1) is bonded to three equivalent Rh(1) and one Cd(1) atom to form AlCdRh3 trigonal pyramids that share corners with three equivalent Cd(1)AlRh6 pentagonal bipyramids.
