Materials Data on AlAgB by Materials Project
AgAlB is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Ag is bonded to four equivalent Al atoms to form distorted AgAl4 tetrahedra that share corners with four equivalent BAl4 tetrahedra, corners with twelve equivalent AgAl4 tetrahedra, and edges with six equivalent BAl4 tetrahedra. All Ag–Al bond lengths are 2.46 Å. Al is bonded in a body-centered cubic geometry to four equivalent Ag and four equivalent B atoms. All Al–B bond lengths are 2.46 Å. B is bonded to four equivalent Al atoms to form distorted BAl4 tetrahedra that share corners with four equivalent AgAl4 tetrahedra, corners with twelve equivalent BAl4 tetrahedra, and edges with six equivalent AgAl4 tetrahedra.
