Pd2AuSn2 crystallizes in the trigonal P3m1 space group. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 8-coordinate geometry to three equivalent Au(1), two equivalent Sn(1), and three equivalent Sn(2) atoms. In the second Pd site, Pd(2) is bonded in a distorted body-centered cubic geometry to two equivalent Au(1), three equivalent Sn(1), and three equivalent Sn(2) atoms. Au(1) is bonded in a 11-coordinate geometry to two equivalent Pd(2), three equivalent Pd(1), three equivalent Sn(1), and three equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to two equivalent Pd(1), three equivalent Pd(2), and three equivalent Au(1) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to three equivalent Pd(1), three equivalent Pd(2), and three equivalent Au(1) atoms.
