Some new silatranes containing an azomethine group as coordinating system in the axial chain are reported. This system is introduced into the chain by the treatment of 3-aminopropylsilatrane with different carbonyl compounds like acetylacetone (1), 2-acetylphenol (2), paeonol (3) and salicylaldehyde (4) in the presence of anhydrous sodium sulphate. All the compounds were characterized by elemental analysis, spectroscopic techniques and X-ray diffraction analysis. The thermal stability of all silatranes was studied by TGA/DTG/DSC techniques, which is in agreement with the Mass spectrometry and X-ray diffraction studies.
Graphical abstractNew silatranes with azomethine functional group in axial chain were derived from widely used 3-aminopropylsilatrane and corresponding carbonyl compounds. These silatranes contain N and O donors, which are capable of coordinating metal ions.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Derivatization of 3-aminopropylsilatrane to form silatranes with azomethine functional group in axial chain. ► Flattening of SiO3 moiety is observed due to pentacoordination of silicon in silatranes. ► Loss of bridging –CH2CH2O– fragments as ethanol is observed in Mass spectrum and TGA. ► Silatranes are capable of coordinating metal ions through N and O. ► The work can be explored in the development of silica surfaces with Schiff base moieties.
