Abstract:
This work was devoted to the synthesis of new hybrid materials formed from hexachloride and difluoruretetrachloride of tin and organic pyridine matrices. The structural study and the physico-chemical characterisation of these compounds were carried out using several techniques such as: proton nuclear magnetic resonance (NMR), Raman and Infrared spectroscopy, X-ray diffraction and differential and gravimetric thermal analysis. Two synthesis methods were used: -Hydrothermal synthesis.- Aqueous synthesis.These investigations on this type of hybrid compounds led to the preparation of several new tin-based phases with different organic matrices:- five pyridine-based products (4-amidopyridin, 3,5-Dichloro-2(1H) pyridinone,4-carboxypyridine, 2-aminopyridin-3-ol and 2-aminopyridin).-Two products based on bipyridine.- A product based on terpyridine (4-chloro-2,6-di (pyridin-3-yl)pyridine). The main purpose of this work is to carry out systematic investigations on new organic-inorganic hybrid compounds in order to prepare new products with interesting properties associated with the mineral and organic parts.
