a Single crystal X-ray molecular structure of the complexes formed from C4v-OC-4 and 1,8-dibromooctane (G1), octane-1,8-dithiol (G2), 1,9-decadiyne (G3), and n-eicosane (G4). These species crystallize as [C4v-OC-4•1,8-dibromooctane], [C4v-OC-4•octane-1,8-dithiol], [C4v-OC-4•1,9-decadiyne], and [2C4v-OC-4⊃n-eicosane], respectively. b Single crystal X-ray diffraction structure of C4v-OC-4כC60 and C4v-OC-4כC70, species that crystalize as [C4v-OC-4•C60•3toluene•2THF] and [C4v-OC-4•C70•2toluene], respectively.
