Materials Data on ZrAlW by Materials Project
ZrAlW is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Zr is bonded to four equivalent W atoms to form distorted ZrW4 tetrahedra that share corners with four equivalent AlW4 tetrahedra, corners with twelve equivalent ZrW4 tetrahedra, and edges with six equivalent AlW4 tetrahedra. All Zr–W bond lengths are 2.76 Å. W is bonded in a body-centered cubic geometry to four equivalent Zr and four equivalent Al atoms. All W–Al bond lengths are 2.76 Å. Al is bonded to four equivalent W atoms to form distorted AlW4 tetrahedra that share corners with four equivalent ZrW4 tetrahedra, corners with twelve equivalent AlW4 tetrahedra, and edges with six equivalent ZrW4 tetrahedra.
