HfPd is Tetraauricupride structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Hf is bonded in a body-centered cubic geometry to eight equivalent Pd atoms. All Hf–Pd bond lengths are 2.88 Å. Pd is bonded in a body-centered cubic geometry to eight equivalent Hf atoms.
HfPd is alpha-derived structured and crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Hf is bonded in a 7-coordinate geometry to seven equivalent Pd atoms. There are a spread of Hf–Pd bond distances ranging from 2.77–2.91 Å. Pd is bonded in a 7-coordinate geometry to seven equivalent Hf atoms.
