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} ( 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 ( symmetry).

Highlights

  • Single crystals of {FeHo6}I12Ho were obtained during the reaction of HoI3 with metallic holmium and iron in a sealed tantalum container
