Cr3Ni is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a distorted body-centered cubic geometry to four equivalent Cr(2) and four equivalent Ni(1) atoms. In the second Cr site, Cr(2) is bonded in a 14-coordinate geometry to eight equivalent Cr(1) and six equivalent Ni(1) atoms. Ni(1) is bonded in a distorted body-centered cubic geometry to six equivalent Cr(2) and eight equivalent Cr(1) atoms.
