NaYb3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Na(1) is bonded in a body-centered cubic geometry to eight equivalent Yb(1) atoms. 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 Na(1) and four equivalent Yb(2) atoms. In the second Yb site, Yb(2) is bonded in a body-centered cubic geometry to eight equivalent Yb(1) atoms.
