Materials Data on HfAu3 by Materials Project
HfAu3 is beta Cu3Ti structured and crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. Hf is bonded to twelve Au atoms to form a mixture of face, edge, and corner-sharing HfAu12 cuboctahedra. There are a spread of Hf–Au bond distances ranging from 2.89–3.05 Å. There are two inequivalent Au sites. In the first Au site, Au is bonded in a 12-coordinate geometry to four equivalent Hf atoms. In the second Au site, Au is bonded in a distorted see-saw-like geometry to four equivalent Hf atoms.
