Via the co-hydrolysis of CrCl, and AlCl, in the presence of swollen Na-montmorillonite, pillared layer clays were prepared. The location of chromium in the pillars and in the primary pillaring agent, the Al,,-Keggin ion, was investigated by various methods (mid and far IR and "Al NMR spectroscopies)

A Wyoming montmorillonite clay has been intercalated using the competitive ion exchange of aluminum hydroxy polycations and oligosilsesquioxanes. Whereas the intercalation of montmorillonite by the products of hydrolysis of trichlorosilylethylpyridine yields an heterogeneous solid, with a large frac
