Abstract

Close
- C60 single crystals compressed at approx. 1 GPa and heated at about 300 C are found to polymerize in one dimension without losing their crystalline order. The resulting structure is orthrhombic, with space group Pmnn and parameters a=9.14 Å, b=9.9 Å and c=14.66 Å. The X-ray single crystal results allow us to derive a polymerization mechanism, which may also, for instance, apply to one dimensional C60 polymers in the doped compounds. The new polymer phase is discussed with respect to the C60 pressure-temperature diagram. The comparison with the A1C60 polymers raises questions about the interchain and the alkali metal - fullerene interactins.
