Abstract

Parallel beam powder data are presented for different phases of the alkali fulleride A1C60 (A=K, Rb). For these phases Rietveld refinement is the only possible method to infer information on the structure because no single crystals are yet available. The wide range of stable and metastable structures include the monomeric, polymeric and dimeric states of the C60 molecule and even a microscopically distributed two-phase mixture. Molecular disorder plays an important role in all cases. The power and limitations of the Rietveld method are discussed in this real set of problems. The deduced structural information ranges from determination of the bare structural skeleton to complete structure solution settling the question of intermolecular bonding.
