Dy2Au2Sn crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded in a 6-coordinate geometry to six equivalent Au and four equivalent Sn atoms. There are two shorter (2.94 Å) and four longer (3.10 Å) Dy–Au bond lengths. All Dy–Sn bond lengths are 3.54 Å. In the second Dy site, Dy is bonded in a 6-coordinate geometry to six equivalent Au and four equivalent Sn atoms. There are two shorter (2.98 Å) and four longer (3.02 Å) Dy–Au bond lengths. All Dy–Sn bond lengths are 3.46 Å. Au is bonded in a 9-coordinate geometry to six Dy and two equivalent Sn atoms. Both Au–Sn bond lengths are 3.12 Å. Sn is bonded to eight Dy and four equivalent Au atoms to form a mixture of distorted corner and face-sharing SnDy8Au4 cuboctahedra.
