PdAu2Cd crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two PdAu2Cd ribbons oriented in the (1, 0, 0) direction. Pd is bonded in a linear geometry to two equivalent Au atoms. Both Pd–Au bond lengths are 2.61 Å. Au is bonded in a linear geometry to one Pd and one Cd atom. The Au–Cd bond length is 2.59 Å. Cd is bonded in a linear geometry to two equivalent Au atoms.
Pd2AuCd is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Pd is bonded in a body-centered cubic geometry to four equivalent Au and four equivalent Cd atoms. All Pd–Au bond lengths are 2.82 Å. All Pd–Cd bond lengths are 2.82 Å. Au is bonded in a distorted body-centered cubic geometry to eight equivalent Pd and six equivalent Cd atoms. All Au–Cd bond lengths are 3.25 Å. Cd is bonded in a distorted body-centered cubic geometry to eight equivalent Pd and six equivalent Au atoms.
