Materials Data on YAl2 by Materials Project
Al2Y is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Y is bonded in a 12-coordinate geometry to four equivalent Y and twelve equivalent Al atoms. All Y–Y bond lengths are 3.41 Å. All Y–Al bond lengths are 3.27 Å. Al is bonded to six equivalent Y and six equivalent Al atoms to form a mixture of edge, face, and corner-sharing AlY6Al6 cuboctahedra. All Al–Al bond lengths are 2.79 Å.
