Materials Data on PrAl2 by Materials Project
PrAl2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Pr is bonded in a 12-coordinate geometry to four equivalent Pr and twelve equivalent Al atoms. All Pr–Pr bond lengths are 3.50 Å. All Pr–Al bond lengths are 3.35 Å. Al is bonded to six equivalent Pr and six equivalent Al atoms to form a mixture of corner, edge, and face-sharing AlPr6Al6 cuboctahedra. All Al–Al bond lengths are 2.86 Å.
