Abstract
Highly saturated lithium-graphite intercalation compounds (of a compos ition LiC2-LiC4) synthesized under high-pressure conditions were inves tigated using X-ray diffraction. It was shown that these compounds pre sent the structure with hexagonal unit cell with a parameter 8.63 Angs trom, c = 3I(c) = 3 . 3.7 = 11.1 Angstrom. The most probable stoichiom etry for this unit cell is LiC2.67, as deduced from the comparison of the calculated and observed intensities of (hkl) reflections. It is su pposed that this structure is the most ''stable'' step in decompositio n of LiC2 compound obtained under pressure.
