The compound described by Er2PtAu crystallizes in the orthorhombic Pmc2_1 space group. There are two inequivalent Er sites. In the first Er site, Er(1) is bonded in a 7-coordinate geometry to four equivalent Pt(1) and three equivalent Au(1) atoms. In the second Er site, Er(2) is bonded in a 7-coordinate geometry to three equivalent Pt(1) and four equivalent Au(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to three equivalent Er(2), four equivalent Er(1), and two equivalent Au(1) atoms. Au(1) is bonded in a 9-coordinate geometry to three equivalent Er(1), four equivalent Er(2), and two equivalent Pt(1) atoms. is represented by the CIF card [CIF]
