AuSc is Tetraauricupride structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sc is bonded in a body-centered cubic geometry to eight equivalent Au atoms. All Sc–Au bond lengths are 2.96 Å. Au is bonded in a body-centered cubic geometry to eight equivalent Sc atoms.
Au3Sc is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sc3+ is bonded to twelve equivalent Au1- atoms to form a mixture of corner and face-sharing ScAu12 cuboctahedra. There are six shorter (2.97 Å) and six longer (2.98 Å) Sc–Au bond lengths. Au1- is bonded in a distorted see-saw-like geometry to four equivalent Sc3+ atoms.
Au2Sc crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sc2+ is bonded in a distorted q6 geometry to ten equivalent Au1- atoms. There are eight shorter (2.91 Å) and two longer (2.99 Å) Sc–Au bond lengths. Au1- is bonded in a 10-coordinate geometry to five equivalent Sc2+ atoms.
Au4Sc crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. Sc2+ is bonded to twelve equivalent Au+0.50- atoms to form a mixture of edge and face-sharing ScAu12 cuboctahedra. There are eight shorter (2.93 Å) and four longer (2.98 Å) Sc–Au bond lengths. Au+0.50- is bonded in a 12-coordinate geometry to three equivalent Sc2+ atoms.
