Ta2CdBi crystallizes in the cubic F-43m space group. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 14-coordinate geometry to four equivalent Ta(2), four equivalent Cd(1), and six equivalent Bi(1) atoms. In the second Ta site, Ta(2) is bonded to four equivalent Ta(1) and four equivalent Bi(1) atoms to form distorted edge-sharing TaTa4Bi4 tetrahedra. Cd(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ta(1) and four equivalent Bi(1) atoms. Bi(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ta(2), six equivalent Ta(1), and four equivalent Cd(1) atoms.
