Ni3Nb is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Nb(1) is bonded in a distorted body-centered cubic geometry to six equivalent Ni(1) and eight equivalent Ni(2) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 14-coordinate geometry to six equivalent Nb(1) and eight equivalent Ni(2) atoms. In the second Ni site, Ni(2) is bonded in a distorted body-centered cubic geometry to four equivalent Nb(1) and four equivalent Ni(1) atoms.
