Holmium dodecaiodidoiron-octahedro-hexaholmium, {FeHo6}I12Ho

K. Daub and G. Meyer

Abstract: Single crystals of {FeHo6}I12Ho were obtained during the reaction of HoI3 with metallic holmium and iron in a sealed tantalum container. The crystal structure consists of isolated holmium clusters encapsulating a single Fe atom, {FeHo6} (\\overline{3} symmetry). The rare earth metal atoms are surrounded by 12 edge-capping and six terminal iodide ligands that either connect the clusters to each other directly or via HoI6 octahedra (\\overline{3} symmetry).
