The structure described by Ti6Os7Al16 crystallizes in the cubic Fm-3m space group. Ti(1) is bonded in a 12-coordinate geometry to four equivalent Os(2), four equivalent Al(1), and four equivalent Al(2) atoms. There are two inequivalent Os sites. In the first Os site, Os(2) is bonded to four equivalent Ti(1), four equivalent Al(1), and four equivalent Al(2) atoms to form a mixture of distorted face and corner-sharing OsTi4Al8 cuboctahedra. In the second Os site, Os(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 Os(2) atoms. In the second Al site, Al(1) is bonded in a 4-coordinate geometry to three equivalent Ti(1), one Os(1), and three equivalent Os(2) atoms. is represented by the CIF file [CIF]
