Materials Data on AlAu by Materials Project

AuAl is Modderite structured and crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Au sites. In the first Au site, Au is bonded in a 6-coordinate geometry to six Al atoms. There are a spread of Au–Al bond distances ranging from 2.64–2.76 Å. In the second Au site, Au is bonded in a 6-coordinate geometry to six Al atoms. There are a spread of Au–Al bond distances ranging from 2.62–2.76 Å. There are two inequivalent Al sites. In the first Al site, Al is bonded in a 6-coordinate geometry to six Au atoms. In the second Al site, Al is bonded in a 6-coordinate geometry to six Au atoms.
