• Electrical resistivity, specific heat and electron diffraction experiments at low temperatures unambiguously reveal that the cubic Cd_6Yb crystal, which is a 1/1 cubic approximant to the recently discovered icosahedral Cd_<5.7>Yb, undergoes a reversible order-disorder transition at about 110 K. The transition is most probably due to the orientational ordering of tetrahedral 4Cd clusters sitting at the center of dodecahedral cages; above 110 K the central 4Cd cluster is disordered over two orientations forming a bcc structure (Im3^^-), whereas below 110 K it is ordered in mixed B2(Pn3^^-) and B32(Fd3^^-m) structures.
