Novel lanthanum(III), europium(III) and terbium(III) compounds of a benzo-15-crown-5 [60]fulleropyrrolidine were isolated in the solid state and characterised using vibrational (infrared and Raman) spectroscopy and by C-13 CP MAS NMR for the lanthanum(III) compound. The photoluminescence properties were investigated for the europium( III) and terbium( III) compounds. The related [Tb(H2O)(3)(NO3)(2)(acac)] . C14H20O5 [where acac(-) = acetylacetonate and C14H20O5 benzo-15-crown-5] supramolecular adduct was isolated using similar synthetic conditions, in the absence of [60]fullerene, and its crystal structure used as a model for the coordination sphere of the lanthanide [60]fullerene derivatives, with further supporting evidence given by photoluminescence measurements.
