The structure described by UPt2Au3 crystallizes in the orthorhombic Imm2 space group. U(1) is bonded in a 16-coordinate geometry to six equivalent Pt(1), four equivalent Au(2), and six equivalent Au(1) atoms. Pt(1) is bonded to three equivalent U(1), two equivalent Pt(1), three equivalent Au(2), and four equivalent Au(1) atoms to form a mixture of corner, face, and edge-sharing PtU3Pt2Au7 cuboctahedra. There are two inequivalent Au sites. In the first Au site, Au(2) is bonded in a 16-coordinate geometry to four equivalent U(1), six equivalent Pt(1), and six equivalent Au(1) atoms. In the second Au site, Au(1) is bonded in a 12-coordinate geometry to three equivalent U(1), four equivalent Pt(1), two equivalent Au(1), and three equivalent Au(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
