The compound described by YAgAl3 crystallizes in the orthorhombic Imm2 space group. Y(1) is bonded in a 16-coordinate geometry to four equivalent Ag(1), four equivalent Al(1), four equivalent Al(2), and four equivalent Al(3) atoms. Ag(1) is bonded in a 12-coordinate geometry to four equivalent Y(1), two equivalent Al(2), two equivalent Al(3), and four equivalent Al(1) atoms. There are three inequivalent Al sites. In the first Al site, Al(1) is bonded to four equivalent Y(1), four equivalent Ag(1), two equivalent Al(2), and two equivalent Al(3) atoms to form a mixture of distorted corner and face-sharing AlY4Al4Ag4 cuboctahedra. In the second Al site, Al(2) is bonded in a 9-coordinate geometry to four equivalent Y(1), two equivalent Ag(1), one Al(3), and two equivalent Al(1) atoms. In the third Al site, Al(3) is bonded in a 9-coordinate geometry to four equivalent Y(1), two equivalent Ag(1), one Al(2), and two equivalent Al(1) atoms. is represented by the CIF file [CIF]
