Bis‐Carbene Adducts of Non‐IPR La₂@C₇₂: Localization of High Reactivity around Fused Pentagons and Electrochemical Properties

Abstract

Candylike fullerene: Two adamantylidene (Ad) groups are covalently bonded to the two fused-pentagon sites of the non-IPR endohedral metallofullerene La2@C72 in bis-adduct La2@C72Ad2. Its open-cage structure, reminiscent of a wrapped candy, was determined by single-crystal X-ray diffraction (see picture), and it retains the electronic structure of pristine La2@C72.
