Materials Data on EuCr3 by Materials Project
EuCr3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Eu is bonded in a distorted body-centered cubic geometry to fourteen Cr atoms. There are eight shorter (3.02 Å) and six longer (3.49 Å) Eu–Cr bond lengths. There are two inequivalent Cr sites. In the first Cr site, Cr is bonded in a distorted body-centered cubic geometry to four equivalent Eu and four equivalent Cr atoms. All Cr–Cr bond lengths are 3.02 Å. In the second Cr site, Cr is bonded in a 8-coordinate geometry to six equivalent Eu and eight equivalent Cr atoms.
