Materials Data on P3W by Materials Project
WP3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. W6+ is bonded in a distorted body-centered cubic geometry to fourteen P2- atoms. There are eight shorter (2.63 Å) and six longer (3.03 Å) W–P bond lengths. There are two inequivalent P2- sites. In the first P2- site, P2- is bonded in a body-centered cubic geometry to four equivalent W6+ and four equivalent P2- atoms. All P–P bond lengths are 2.63 Å. In the second P2- site, P2- is bonded in a 8-coordinate geometry to six equivalent W6+ and eight equivalent P2- atoms.
