KYb3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. K(1) is bonded in a body-centered cubic geometry to six equivalent Yb(2) and 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 K(1) and four equivalent Yb(2) atoms. In the second Yb site, Yb(2) is bonded in a 14-coordinate geometry to six equivalent K(1) and eight equivalent Yb(1) atoms.
