The compound described by Ce2Y(PdAl)3 crystallizes in the orthorhombic Amm2 space group. Ce(1) is bonded in a 5-coordinate geometry to one Pd(2) and four equivalent Pd(1) atoms. Y(1) is bonded in a 5-coordinate geometry to one Pd(2) and four equivalent Pd(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), two equivalent Y(1), one Al(1), and two equivalent Al(2) atoms. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to two equivalent Ce(1), one Y(1), two equivalent Al(1), and four equivalent Al(2) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 4-coordinate geometry to two equivalent Pd(1) and two equivalent Pd(2) atoms. In the second Al site, Al(2) is bonded in a 4-coordinate geometry to two equivalent Pd(1) and two equivalent Pd(2) atoms. is represented by the CIF file [CIF]
