Abstract
This study focuses on the synthesis and structural determination of complexes formed between boron compounds and Schiff bases. In this study 26 ON, ONO, ONNO and ONS type Schiff bases together with reduced forms were used and twelve boron complexes were synthesized. The structure of synthesized boron complexes whose structrure is appropriate for X-ray data collection was identified by X-ray diffraction method, IR spectroscopy, termogravimetric and elemental analyses. Crystal structures which are not suitable for X-ray data collection were compared to IR and termogravimetric spectra of complexes whose structures were identified and consequently their possible structures were determined by paying attention to similar structrures reported in the literature.In addition, some Schiff bases, which have been precipitated as powder and which have not been crystalized in enough growth for X-ray data collection, did not yield boron complexes in boric or phenylboronic acids media. However, it was observed that they yielded crystals suitable for X-ray data collection using the acids as catalysts.
