Materials Data on PPbW by Materials Project

WPbP is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. W is bonded in a 4-coordinate geometry to four equivalent Pb and six equivalent P atoms. All W–Pb bond lengths are 2.86 Å. All W–P bond lengths are 3.31 Å. Pb is bonded in a body-centered cubic geometry to four equivalent W and four equivalent P atoms. All Pb–P bond lengths are 2.86 Å. P is bonded to six equivalent W and four equivalent Pb atoms to form a mixture of distorted corner and face-sharing PPb4W6 tetrahedra.
