y
in which x=1 or 2, y=3−x, X being a halogen and R designating at least one organic alkyl, aryl or aryl-alkyl group.
Non-exhaustive applications for the hybrid organic-inorganic material obtained by the process of the invention are in the fields of anti-corrosion, lubrication, microelectronics, nanotechnologies, composite materials, heterogeneous catalysis, supported catalysis, depollution and biomedical applications.
