Ce2CdSb4 crystallizes in the tetragonal P-4m2 space group. Ce(1) is bonded in a 10-coordinate geometry to two equivalent Cd(1), two equivalent Sb(2), two equivalent Sb(3), and four equivalent Sb(1) atoms. Cd(1) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Sb(1) atoms. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to four equivalent Ce(1) and two equivalent Cd(1) atoms to form a mixture of distorted corner, face, and edge-sharing SbCe4Cd2 pentagonal pyramids. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Sb(3) atoms. In the third Sb site, Sb(3) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Sb(2) atoms.
