Materials Data on MgAlSi by Materials Project
AlMgSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Mg is bonded in a 5-coordinate geometry to four equivalent Al and five equivalent Si atoms. There are two shorter (3.04 Å) and two longer (3.12 Å) Mg–Al bond lengths. There are a spread of Mg–Si bond distances ranging from 2.81–2.93 Å. Al is bonded in a 4-coordinate geometry to four equivalent Mg and four equivalent Si atoms. There are a spread of Al–Si bond distances ranging from 2.57–2.63 Å. Si is bonded in a 9-coordinate geometry to five equivalent Mg and four equivalent Al atoms.
