Materials Data on PrW3 by Materials Project
PrW3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Pr is bonded in a distorted body-centered cubic geometry to fourteen W atoms. There are eight shorter (2.90 Å) and six longer (3.35 Å) Pr–W bond lengths. There are two inequivalent W sites. In the first W site, W is bonded to four equivalent Pr and four equivalent W atoms to form a mixture of distorted corner, edge, and face-sharing WPr4W4 tetrahedra. All W–W bond lengths are 2.90 Å. In the second W site, W is bonded in a 8-coordinate geometry to six equivalent Pr and eight equivalent W atoms.
