Description

By means of interaction between H2[ReOX5] (X = Cl, Br) in concentrated solutions of HX and pyridylbenzimidazole (L) rhenium(V) complexes of the composition trans-[ReOLX3]·2H2O, trans-[ReOL2X]X2·2H2O, [ReOLX2(OH)] and [ReOL2(OH)]X2 were prepared. The products were characterized by the methods of elementary and thermal analyses, IR spectroscopy and conductometry. Synthesis conditions were defined, which give rise to rhenium(V) complexes formation with bidentate coordination of one and two L molecules. Phenomenon of trans-cis-isomerism was revealed, thermodynamic characteristics of the transitions were ascertained

Abstract (Russian)

Взаимодействием H2[ReOX5] (X = Cl, Br) в концентрированных растворах НХ с пиридилбензимидазолом (L) получены комплексы рения(V) состава транс-[ReOLX3]·2H2O, транс-[ReOL2X]X2·2H2O, [ReOLX2(OH)] и [ReOL2(OH)]X2. Продукты охарактеризованы методами элементного и термического анализа, ИК спектроскопии и кондуктометрии. Определены условия синтеза, при которых образуются комплексы рения(V) с бидентатной координацией одной и двух молекул L. Установлено явление транс-цис-изомерии, получены термодинамические характеристики этих переходов
