Ti6Rh7Al16 crystallizes in the cubic Fm-3m space group. Ti(1) is bonded in a 16-coordinate geometry to four equivalent Ti(1), 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 in a 8-coordinate geometry to four equivalent Ti(1), four equivalent Al(1), and four equivalent Al(2) atoms. 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 Ti(1) and three equivalent Rh(2) atoms. In the second Al site, Al(1) is bonded to three equivalent Ti(1), one Rh(1), and three equivalent Rh(2) atoms to form a mixture of distorted face, corner, and edge-sharing AlTi3Rh4 tetrahedra.
