Materials Data on ZnCr3 by Materials Project
Cr3Zn is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Cr sites. In the first Cr site, Cr is bonded in a distorted body-centered cubic geometry to four equivalent Cr and four equivalent Zn atoms. All Cr–Cr bond lengths are 2.57 Å. All Cr–Zn bond lengths are 2.57 Å. In the second Cr site, Cr is bonded in a distorted body-centered cubic geometry to eight equivalent Cr atoms. Zn is bonded in a distorted body-centered cubic geometry to eight equivalent Cr atoms.
