文摘

The silicon (IV) compounds possessing SiN₄O₂ (6), SiN₂O₂C₂ (7, 8), SiN₂O₂CCl (9) and SiN₄O₄ (10) coordinating frameworks have been synthesized in high yield by the reaction of the O,N,N,O- donor salen-type ligand N,N’-bis(salicylidene)ethylenediimine L with different silanes i.e. diethoxydiisocyanatosilane-(C₂H₅O)₂Si(NCO)₂1, dichlorodiphenylsilane-Ph₂SiCl₂2, dichloromethyl- phenylsilane-MePhSiCl₂3, trichlorophenylsilane-PhSiCl₃4 and silicon tetrachloride-SiCl₄5. The compounds 6–10 have been characterized by elemental analysis, IR, 1H, 13C and 29Si NMR and mass spectrometry. The decomposition reactivity of these compounds has been studied using a Thermal Gravimetric Analyzer (TGA) at a heating rate of 10°C/minute in an inert atmosphere.
