Applying different synthetic routes, a series of novel polyanions endohedral filled with transition metal atoms of Group 9 such as [Co@Sn₉]^4-, [Co₂@Sn₁₇]^5-, [Rh@Sn₁₀]^3-, [Ir@Sn₁₂]^3- have been isolated. These clusters were directly obtained as K salts from the extraction of the corresponding ternary intermetallic compound precursors having different nominal compositions. Beside structural characterization by means of single crystal X-ray diffraction methods, several compounds were investigated by ESI-MS, EPR and Raman spectroscopy.     «
