Beschreibungen/Notizen

• The title compounds were synthesized and their crystal structures determined by single crystal X-ray diffraction data. Both compounds crystallize with the cubic space group Im3̄̅. Yb(Zn,Al) : a = 14.299(4) Å , wR(F ) = 0.041, with Yb Zn Al as the refined composition; YbZn : a = 14.298(4) Å , wR(F ) = 0.079, with Yb Zn as the refined composition. Their crystal structures are closely related to the YCd type, with two different details: Zn/Al (or Zn) atoms in the 8c sites center the cubic interstices of the structure; the pentagonal dodecahedron cavities are partially filled by ytterbium atoms in the 2a sites, with an environment topologically similar to that found in the clathrate-I compounds. Magnetic properties of the two compounds are also reported.
