The crystal structure described by ErY(Pd2Sn)2 is Tungsten-derived structured and crystallizes in the trigonal R-3m space group. Er(1) is bonded in a body-centered cubic geometry to two equivalent Pd(2); six Pd(1,1); and six equivalent Sn(1) atoms. Y(1) is bonded in a body-centered cubic geometry to two equivalent Pd(1); six Pd(2,2); and six equivalent Sn(1) atoms. There are six inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a body-centered cubic geometry to three equivalent Er(1), one Y(1), and four equivalent Sn(1) atoms. In the second Pd site, Pd(2) is bonded in a body-centered cubic geometry to one Er(1), three equivalent Y(1), and four equivalent Sn(1) atoms. In the third Pd site, Pd(2) is bonded in a body-centered cubic geometry to one Er(1), three equivalent Y(1), and four equivalent Sn(1) atoms. In the fourth Pd site, Pd(1) is bonded in a body-centered cubic geometry to three equivalent Er(1), one Y(1), and four equivalent Sn(1) atoms. In the fifth Pd site, Pd(1) is bonded in a body-centered cubic geometry to three equivalent Er(1), one Y(1), and four equivalent Sn(1) atoms. In the sixth Pd site, Pd(2) is bonded in a body-centered cubic geometry to one Er(1), three equivalent Y(1), and four equivalent Sn(1) atoms. Sn(1) is bonded in a distorted body-centered cubic geometry to three equivalent Er(1); three equivalent Y(1); four Pd(1,1); and four Pd(2,2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
