The adduct C 60 ·(Ptol 3 ) 2 AuNO 3 has been crystallized from toluene solutions of C 60 and (Ptol 3 ) 2 AuNO 3 as violet, trigonal plate‐shaped crystals. The compound was studied by single‐crystal x‐ray diffraction ( $P{\bar 3}{\rm 1}c$ , a = 1278.17(3), c = 2282.92(6) pm). The gold complex is dissociated into [(Ptol 3 ) 2 Au] + cations, which encapsulate the neutral C 60 molecules, and nitrate anions. The intermolecular interactions between the fullerene molecules and the gold complex cations and the resulting disorder is investigated. The crystal structure of C 60 ·(Ptol 3 ) 2 AuNO 3 is providing an instructive example, demonstrating that symmetry‐matching is not always sufficient for avoiding disorder.
