✦ Synopsis

Solutions of lithium or sodium in hexamethylphosphoramide

react with graphite to give ternary lamellar compounds, with "ideal" formulas Li(S)C,, and Na(S)C,, respectively, where (S) represents a molecule of solvent. Since the solutions of the alkali metals are relatively unstable, the reaction must be carried out with complete exclusion of oxygen and water-vapor. X-ray diffraction studies (Debye-Scherrer) show that both compounds are first-stage, with the following parameters :

The isotherm of bromine on pyrolytic graphite was studied at 20Β°C by stepwise bromination, and several phases of graphite bromide were identified, which have compositions of C,Br, C,\*Br, C16Br and C,,,Br. X-ray studies show that these possess the socalled 2nd, 3rd, 4th and 5th stage structures resp
