GdPd crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Gd is bonded in a 7-coordinate geometry to seven equivalent Pd atoms. There are a spread of Gd–Pd bond distances ranging from 2.97–3.06 Å. Pd is bonded in a 7-coordinate geometry to seven equivalent Gd atoms.
GdPd3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Gd is bonded to twelve equivalent Pd atoms to form a mixture of corner and face-sharing GdPd12 cuboctahedra. All Gd–Pd bond lengths are 2.94 Å. Pd is bonded in a distorted square co-planar geometry to four equivalent Gd atoms.
Gd3Pd2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. there are two inequivalent Gd sites. In the first Gd site, Gd is bonded in a 6-coordinate geometry to six equivalent Pd atoms. There are two shorter (3.02 Å) and four longer (3.08 Å) Gd–Pd bond lengths. In the second Gd site, Gd is bonded in a square co-planar geometry to four equivalent Pd atoms. All Gd–Pd bond lengths are 3.10 Å. Pd is bonded in a 8-coordinate geometry to eight Gd atoms.
