Materials Data on Sr3W by Materials Project
Sr3W is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Sr sites. In the first Sr site, Sr is bonded to four equivalent Sr and four equivalent W atoms to form a mixture of distorted face, edge, and corner-sharing SrSr4W4 tetrahedra. All Sr–Sr bond lengths are 3.58 Å. All Sr–W bond lengths are 3.58 Å. In the second Sr site, Sr is bonded in a 8-coordinate geometry to eight equivalent Sr and six equivalent W atoms. All Sr–W bond lengths are 4.13 Å. W is bonded in a distorted body-centered cubic geometry to fourteen Sr atoms.
