The crystal structure described by Sm2Cu2Cd crystallizes in the tetragonal P4/mbm space group. Sm(1) is bonded in a 10-coordinate geometry to six equivalent Cu(1) and four equivalent Cd(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1), one Cu(1), and two equivalent Cd(1) atoms. Cd(1) is bonded to eight equivalent Sm(1) and four equivalent Cu(1) atoms to form a mixture of face and corner-sharing CdSm8Cu4 cuboctahedra. is represented by the CIF card [CIF]
