Abstract

The first examples of high-nuclear 3d–4f heterometallic clusters with mixed amino acid ligands are reported. Four 30-nuclear clusters {Ln6Cu24}(Ln = Gd, Tb, Pr and Sm) were obtained through the self-assembly of LnIII, CuII and mixed amino acid ligands of glycine (HGly) and β-alanine (HAla). The metal skeleton of clusters 1–4 may be described as a huge {Ln6Cu12} octahedron connected with 12 additional CuII ions. The temperature dependence of magnetic susceptibilities of compounds 1–4 were also studied.
