    Аннотация

    Changes in the electronic structure of SbCI5L complexes during their formation have been studied and compared with corresponding earlier data for SnCl4L2 and TiCl4L2 complexes. Analysis of the results of X-ray structural studies, against data on the heat of complex formation, the Mossbauer effect, results of PM3 quantum chemical calculations, derivatographic data and the frequencies of valence vibrations, permitted assessment of the complex stability against different factors and determination of the enthalpies of complex formation, and proved that the transfer of electron density from donor to acceptor was small. The charge of the donor is proved to affect mainly the polarization of the acceptor bonds.
