| Abstract: | Potassium reduction of iron– and ruthenium–penta(organo)60]fullerene complexes, M(η5‐C60R5)(η5‐Cp)] ( 1 a : M=Fe, R=Ph; 1 b : M=Fe, R=Me; 1 c : M=Ru, R=Ph; 1 d : M=Ru, R=Me; Cp=C5H5) gave mono‐ and dianions of these complexes. Treatment of the dianion 1 a with α‐bromodiphenylmethane gave three different iron–hepta(organo)60]fullerenes, Fe{η5‐C60Ph5(CHPh2)2}(η5‐Cp)], as a mixture of regioisomers. All three compounds were fully characterized by physical methods, including X‐ray crystallography and electrochemical measurements. One of the three compounds contains a new hoop‐shaped condensed aromatic system. |
