The Materials Project

Hf2Al3 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. Hf is bonded in a 7-coordinate geometry to nine Al atoms. There are a spread of Hf–Al bond distances ranging from 2.84–3.17 Å. There are two inequivalent Al sites. In the first Al site, Al is bonded in a 10-coordinate geometry to six equivalent Hf and four equivalent Al atoms. There are two shorter (2.66 Å) and two longer (2.70 Å) Al–Al bond lengths. In the second Al site, Al is bonded in a 10-coordinate geometry to six equivalent Hf and four Al atoms. Both Al–Al bond lengths are 2.77 Å.
