Materials Data on Hf3AlAu2 by Materials Project
Hf3Au2Al crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Hf is bonded in a 2-coordinate geometry to four equivalent Au atoms. There are two shorter (2.84 Å) and two longer (3.08 Å) Hf–Au bond lengths. Au is bonded in a 9-coordinate geometry to six equivalent Hf and three equivalent Al atoms. All Au–Al bond lengths are 2.71 Å. Al is bonded to six equivalent Au atoms to form distorted edge-sharing AlAu6 cuboctahedra.
