The crystal structure described by Yb3Cd 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 to four equivalent Yb(2) and four equivalent Cd(1) atoms to form a mixture of distorted edge, face, and corner-sharing YbYb4Cd4 tetrahedra. In the second Yb site, Yb(2) is bonded in a 14-coordinate geometry to eight equivalent Yb(1) and six equivalent Cd(1) atoms. Cd(1) is bonded in a body-centered cubic geometry to six equivalent Yb(2) and eight equivalent Yb(1) atoms. is represented by the CIF card [CIF]
