Sc6Rh7Al16 crystallizes in the cubic Fm-3m space group. Sc(1) is bonded in a 12-coordinate geometry to four equivalent Rh(2), four equivalent Al(1), and four equivalent Al(2) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded to four equivalent Sc(1), four equivalent Al(1), and four equivalent Al(2) atoms to form a mixture of distorted face and corner-sharing RhSc4Al8 cuboctahedra. In the second Rh site, Rh(1) is bonded in a body-centered cubic geometry to eight equivalent Al(1) atoms. There are two inequivalent Al sites. In the first Al site, Al(2) is bonded in a distorted trigonal planar geometry to three equivalent Sc(1) and three equivalent Rh(2) atoms. In the second Al site, Al(1) is bonded in a 4-coordinate geometry to three equivalent Sc(1), one Rh(1), and three equivalent Rh(2) atoms.
