A highly saturated Li graphite intercalation compound synthesized under high pressure, was investigated after pressure relaxation by Li-7 NMR spectroscopy At low temperature the sample exhibits a doublet at 256 ppm downfield from Li+. The lineshape agrees with the simulation of an island of 7 Li atoms with nearest neighbours at 2.46 Angstrom distances, in good agreement with a local LiC2 structure. This confirms short metal-metal bondlengths and possible Li-Li covalent bonds which were shown by IR Spectroscopy.
