Li4C60: A Polymeric Fulleride with a Two-Dimensional Architecture and Mixed Interfullerene Bonding Motifs.

The article presents information on Li4c60, a polymeric fulleride with a two-dimensional architecture and mixed interfullerene bonding motifs. An unexpected discovery in fullerene chemistry has been the ease with which C60 units can covalently bond together to give rise to polymerized fullerene networks with a variety of structural architectures. No anomalous close contacts between either the alkali ions or between Li+ and the C60 units are encountered.
