We show that electron transfer from the perchlorotriphenylmethide anion (PTM − ) to Y@C 82 ( C 2 v ) is an instantaneous process, suggesting potential applications for using PTM − to perform redox titrations of numerous endohedral metallofullerenes. The first representative of a Y@C 82 ‐based salt containing the complex cation was prepared by treating Y@C 82 ( C 2 v ) with the [K + ([18]crown‐6)]PTM − salt. The synthesis developed involves the use of the [K + ([18]crown‐6)]PTM − salt as a provider of both a complex cation and an electron‐donating anion that is able to reduce Y@C 82 ( C 2 v ). For the first time, the molar absorption coefficients for neutral and anionic forms of the pure isomer of Y@C 82 ( C 2 v ) were determined in organic solvents with significantly different polarities.
