Materials Data on YAlSi by Materials Project
AlSiY crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Y is bonded in a 2-coordinate geometry to four equivalent Al and five equivalent Si atoms. All Y–Al bond lengths are 3.18 Å. There are a spread of Y–Si bond distances ranging from 2.93–3.03 Å. Al is bonded in a 12-coordinate geometry to four equivalent Y and four equivalent Si atoms. All Al–Si bond lengths are 2.67 Å. Si is bonded in a 9-coordinate geometry to five equivalent Y and four equivalent Al atoms.
