Abstract

We report the synthesis, structure and magnetic properties of the first rare earth complexes of metalloid group 14 clusters [(thf)₂Ln(Ge₉Hyp₃)₂] (Ln = Eu, Sm, Hyp = Si(SiMe₃)₃). X-Ray crystallographic analysis and DFT calculations reveal a novel η²-coordination mode of the Ge₉Hyp₃ units and a slight distortion of the Ge₉ cage.
