摘要：

Second and higher stage graphite derivatives of three alkali metals reversibly react with polar molecules such as tetrahydrofuran (THF). For the second stage binary derivatives the compounds formed are MC24Xp wher M is K, Rb or Cs and X is the organic molecule. When X is THF, p is 1 (Ic = 7.16 A ̊), 2(Ic = 8.88 A ̊) or 3 (Ic = 8.95 A ̊) depending on the experimental conditions. Since the Ic values are practically independent of the nature of M it appears that in all cases the metal ion (or atom) is lodged within cavities between the organic molecules whose dimensions and orientations are solely responsible for the Ic values. © 1979.
