Склад, будова і термічні властивості комплексних тетрафтороборатів металів з нітрогенвмісними органічними основами

Abstract

The thermal properties of zinc(II), cadmium(II) and plumbum(II) tetrafluoroborate complexes with nitrogen organic bases have been found by thermogravimetric analysis. The schemes of the thermal dissociation was proposed. It was shown that the tetrafluoroborate-ion character definite the stoichiometry of the final and intermediate products of the thermolise. It allowed to use thermogravimetric analysis for the assertion of anion state in the coordinating compounds. It was marked that the increase of the organic ligand bacisity and the “semi-coordinating” of BF, lead to the thermal stabilization of the tetrafluoroborate complexes.
