The material described by Au3Y is beta Cu3Ti structured and crystallizes in the orthorhombic Pmmn space group. Y(1) is bonded to four equivalent Au(2) and eight equivalent Au(1) atoms to form a mixture of edge, face, and corner-sharing YAu12 cuboctahedra. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 4-coordinate geometry to four equivalent Y(1) atoms. In the second Au site, Au(2) is bonded in a distorted see-saw-like geometry to four equivalent Y(1) atoms. is represented by the CIF card [CIF]
