Abstract
The ternary ordered Laves phases CeNi4Cd and RECu4Cd (RE = Ho, Er, Tm, Yb) were synthesized by induction-melting of the elements in sealed tantalum tubes. The compounds were characterized by X-ray powder and single crystal diffraction: MgCu4Sn type, F 4̄3m, a = 706.9(2) pm for CeNi4Cd, a = 723.1(2) pm for HoCu4Cd, a = 717.7(3) pm for ErCu4Cd, a = 714.2(1) pm for TmCu4Cd, and a = 713.10(7) pm for YbCu4Cd. The nickel and copper atoms build up threedimensional networks of corner-sharing Ni4/2 and Cu4/2 tetrahedra. These networks leave voids of coordination number 16 that are filled with the rare earth (RE) and cadmium atoms.
