Abstract
Surface chromium (II) on silica is coordinated by two ≥SiO groups in cis position. Adsorption of ammonia and amines leads to stable (≥SiO)2CrL2 and further to unstable (≥SiO)2CrL4; reflection spectra suggest pseudo square planar and pseudo octahedral structures respectively for these complexes. Formation of the six-coordinate species depends on the type of the amine.
Abstract
Поверхностный хром (II) на окиси алюминия координирован в положениицис двумя группами ≥SiO. Адсорбция аммония и аминов приводит к образованию стабильного (≥SiO)2CrL2 и нестабильного (≥SiO)2CrL4; на основе спектров отражения для этих комллексов полагается псевдоквадратноплоская и псевдооктаэдрическая структура, соответственно. Образование соединений с координационным числом шесть зависнт от типа амина.
