Комплексообразование непереходных элементов в водных растворах

Комплексообразование непереходных элементов в водных растворах

Abstract

The complexation schem for Sb(III) C4H6O6 H2O system can be present as a step-wise deprotonation of complexes with the increase of pH accompanied by the formation of bisligand complexes of neutral solutions and dimmers in alkali one. The structure of Sb(III) tartaric complexes has been studied by IR spectroscopy method of water solutions in combination with quantum-chemical calcu-lations. We have concluded that the complexation at pH 6,0 is a result of the formation of coordinational bonds with two carboxyl groups of the tartaric acid. In alkali solutions, all the functional groups of the tartaric acid form coordinational bonds with Sb(III)

Настоящая работа продолжает цикл публикаций по изучению комплексообразования не-переходных элементов в водных растворах. Изучено комплексообразование сурьмы в вод-ных растворах с винной кислотой в качестве лиганда методом инфракрасной спектро-скопии водных растворов в сочетании с квантово-химическими расчетами. Получены данные об образовании гидроксои биядерных форм комплексов сурьмы(III) и установле-но, с какими функциональными группами лиганда связывается металл в нейтральной и щелочной средах.
