The crystal structure described by CeAgAl3 crystallizes in the tetragonal I4mm space group. Ce(1) is bonded in a 16-coordinate geometry to four equivalent Ag(1), four equivalent Al(2), and eight equivalent Al(1) atoms. Ag(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), one Al(2), and four equivalent Al(1) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 2-coordinate geometry to four equivalent Ce(1), two equivalent Ag(1), and two equivalent Al(2) atoms. In the second Al site, Al(2) is bonded in a distorted single-bond geometry to four equivalent Ce(1), one Ag(1), and four equivalent Al(1) atoms. is represented by the CIF card [CIF]
