The process of equilibrium intercalation compounds formation based on layered inorganic crystal by organic molecules introduction into interlayer gaps has been first studied. Using the X-ray analysis in situ, the equilibruim intercalation phase has been shown to be formed via a series consecutive structure-chemical transformations. The intermediate states are a set of variuos long-periodic structures. In the course of intercalation, the initial textured film of the layered crystal undergo dispersion forming fragments of scale-like shape having characteristic dimension of several tens of Angstroms.
