Description

Heteropoly complexes Na0.5Cs2-x[H0.5-xFexCr(OH)6Mo6O18] · 7H2O (x = 0.19) and Na0.5Cs2-x [H0.5-xFexAl(OH)6Mo6O18] · 8H2O (x = 0.25) were studied by Moessbauer spectroscopy and magnetochemistry. The iron in these complexes was found to be in a distorted octahedral environment. The iron oxidation state (+2) was confirmed. According to the isomer shifts δ, the heteropoly ligands were arranged in a nepheloxetic series with the increasing bond covalence

Abstract (Russian)

Проведено исследование гетерополикомплексов Na0.5Cs2-x[H0.5-xFexCr(OH)6Mo6O18] · 7Н2О (х =0.19) и Na0.5Cs2-x[H0.5-xFexAl(OH)6Mo6O18] · 8H2O (х = 0.25) методами спектроскопии ЯГР и магнетохимии. Показано, что железо в структуре этих комплексов находится в искаженном октаэдрическом окружении. Подтверждена степень окисления железа, равная +2. На основании величины изомерного сдвига δ гетерополилиганды могут быть расположены в нефелоксетический ряд по мере роста ковалентности связи
