AuDy2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to four equivalent Au(1) atoms to form a mixture of corner and edge-sharing DyAu4 tetrahedra. In the second Dy site, Dy(2) is bonded in a 3-coordinate geometry to three equivalent Au(1) atoms. Au(1) is bonded in a 7-coordinate geometry to three equivalent Dy(2) and four equivalent Dy(1) atoms.
AuDy2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to four equivalent Au(1) atoms to form a mixture of corner and edge-sharing DyAu4 tetrahedra. There are a spread of Dy(1)-Au(1) bond distances ranging from 2.88-3.04 Å. In the second Dy site, Dy(2) is bonded in a 3-coordinate geometry to three equivalent Au(1) atoms. There is one shorter (2.90 Å) and two longer (3.14 Å) Dy(2)-Au(1) bond lengths. Au(1) is bonded in a 7-coordinate geometry to three equivalent Dy(2) and four equivalent Dy(1) atoms.
