Evolution structurale de la nacrite en fonction de la nature des molécules organiques intercalees

Using X-ray diffraction and infrared spectroscopy, the structures of the intercalated compounds of nacrite with dimethyl sulfoxide (DMSO) and N-methylacetamide (NMA) have been determined, including the mutual positions of the layers after intercalation and the positions of the intercalated molecules in the interlayer space. It has been shown that the intercalation process causes not only a swelling of the interlayer space but also a shift in the mutual in-plane positions of the layers.
