Materials Data on KSr3 by Materials Project
KSr3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. K is bonded in a body-centered cubic geometry to eight equivalent Sr atoms. All K–Sr bond lengths are 4.24 Å. There are two inequivalent Sr sites. In the first Sr site, Sr is bonded in a body-centered cubic geometry to four equivalent K and four equivalent Sr atoms. All Sr–Sr bond lengths are 4.24 Å. In the second Sr site, Sr is bonded in a body-centered cubic geometry to eight equivalent Sr atoms.
