The structure described by Ho2Cu2Cd crystallizes in the tetragonal P4/mbm space group. Ho(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 Ho(1), one Cu(1), and two equivalent Cd(1) atoms. Cd(1) is bonded to eight equivalent Ho(1) and four equivalent Cu(1) atoms to form a mixture of face and corner-sharing CdHo8Cu4 cuboctahedra. is represented by the CIF card [CIF]
