Yb3Hf is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a distorted body-centered cubic geometry to four equivalent Yb(2) and four equivalent Hf(1) atoms. In the second Yb site, Yb(2) is bonded in a 14-coordinate geometry to eight equivalent Yb(1) and six equivalent Hf(1) atoms. Hf(1) is bonded in a distorted body-centered cubic geometry to six equivalent Yb(2) and eight equivalent Yb(1) atoms.
