ScPd3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sc is bonded to twelve equivalent Pd atoms to form a mixture of face and corner-sharing ScPd12 cuboctahedra. All Sc–Pd bond lengths are 2.84 Å. Pd is bonded in a distorted square co-planar geometry to four equivalent Sc atoms.
PdSc 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 Pd atoms. All Sc–Pd bond lengths are 2.87 Å. Pd is bonded in a body-centered cubic geometry to eight equivalent Sc atoms.
Sc2Pd crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. there are two inequivalent Sc sites. In the first Sc site, Sc is bonded in a 6-coordinate geometry to six equivalent Pd atoms. All Sc–Pd bond lengths are 2.76 Å. In the second Sc site, Sc is bonded in a 2-coordinate geometry to two equivalent Pd atoms. Both Sc–Pd bond lengths are 2.85 Å. Pd is bonded in a 9-coordinate geometry to six Sc atoms.
