Abstract

The long-missing stoichiometric phase of Na4 C60 has been identified by Rietveld analysis of synchrotron powder diffraction data. Its monoclinic structure is based on polymer planes of C60 where each molecule forms four “single” bonds within the plane. This compound is not only the first fulleride polymer with such bonds, but also the first two-dimensional polymer which is naturally intercalated with alkali ions and can be synthesized at ambient pressure. Na4 C60 is a metal and is expected to be a prototype structure where electronic overlap between the planes can be tuned by the alkali cation size.
