Materials Data on ScAl2 by Materials Project
Al2Sc is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Sc is bonded in a 12-coordinate geometry to four equivalent Sc and twelve equivalent Al atoms. All Sc–Sc bond lengths are 3.28 Å. All Sc–Al bond lengths are 3.15 Å. Al is bonded to six equivalent Sc and six equivalent Al atoms to form a mixture of corner, edge, and face-sharing AlSc6Al6 cuboctahedra. All Al–Al bond lengths are 2.68 Å.
