The crystal structure described by ErCuCd2 is Bergman Structure: Mg32(Al,Zn)49 Bergman-like structured and crystallizes in the orthorhombic Cmcm space group. Er(1) is bonded in a 12-coordinate geometry to four equivalent Cu(1) and eight equivalent Cd(1) atoms. Cu(1) is bonded in a 12-coordinate geometry to four equivalent Er(1) and eight equivalent Cd(1) atoms. Cd(1) is bonded in a 11-coordinate geometry to four equivalent Er(1), four equivalent Cu(1), and three equivalent Cd(1) atoms. is represented by the CIF file [CIF]
