Materials Data on Dy2Au by Materials Project
AuDy2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded to four equivalent Au atoms to form a mixture of edge and corner-sharing DyAu4 tetrahedra. There are a spread of Dy–Au bond distances ranging from 2.90–3.05 Å. In the second Dy site, Dy is bonded in a 3-coordinate geometry to five equivalent Au atoms. There are a spread of Dy–Au bond distances ranging from 2.96–3.62 Å. Au is bonded in a 9-coordinate geometry to nine Dy atoms.
