The compound described by Yb5Cu2Cd crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 4-coordinate geometry to four equivalent Cu(1) and two equivalent Cd(1) atoms. In the second Yb site, Yb(2) is bonded to three equivalent Cu(1) and two equivalent Cd(1) atoms to form a mixture of distorted corner, face, and edge-sharing YbCd2Cu3 trigonal bipyramids. Cu(1) is bonded in a 9-coordinate geometry to two equivalent Yb(1), six equivalent Yb(2), and one Cu(1) atom. Cd(1) is bonded in a 10-coordinate geometry to two equivalent Yb(1) and eight equivalent Yb(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
