Materials Data on FePbW2 by Materials Project
W2FePb crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent W sites. In the first W site, W is bonded in a 8-coordinate geometry to four equivalent W, six equivalent Fe, and four equivalent Pb atoms. All W–W bond lengths are 2.78 Å. All W–Fe bond lengths are 3.21 Å. All W–Pb bond lengths are 2.78 Å. In the second W site, W is bonded to four equivalent W and four equivalent Fe atoms to form distorted edge-sharing WFe4W4 tetrahedra. All W–Fe bond lengths are 2.78 Å. Fe is bonded in a distorted body-centered cubic geometry to ten W and four equivalent Pb atoms. All Fe–Pb bond lengths are 2.78 Å. Pb is bonded in a distorted body-centered cubic geometry to four equivalent W and four equivalent Fe atoms.
