Y3Au2 crystallizes in the tetragonal P4/mbm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a square co-planar geometry to four equivalent Au(1) atoms. In the second Y site, Y(2) is bonded in a 6-coordinate geometry to six equivalent Au(1) atoms. Au(1) is bonded in a 8-coordinate geometry to two equivalent Y(1) and six equivalent Y(2) atoms.
Y3Au2 crystallizes in the tetragonal P4/mbm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a square co-planar geometry to four equivalent Au(1) atoms. All Y(1)-Au(1) bond lengths are 3.17 Å. In the second Y site, Y(2) is bonded in a 6-coordinate geometry to six equivalent Au(1) atoms. There are two shorter (3.03 Å) and four longer (3.08 Å) Y(2)-Au(1) bond lengths. Au(1) is bonded in a 8-coordinate geometry to two equivalent Y(1) and six equivalent Y(2) atoms.
