The crystal structure described by Er2Pd2Cd crystallizes in the tetragonal P4/mbm space group. Er(1) is bonded in a 6-coordinate geometry to six equivalent Pd(1) and four equivalent Cd(1) atoms. Pd(1) is bonded in a 9-coordinate geometry to six equivalent Er(1), one Pd(1), and two equivalent Cd(1) atoms. Cd(1) is bonded to eight equivalent Er(1) and four equivalent Pd(1) atoms to form a mixture of distorted face and corner-sharing CdEr8Pd4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
