The Main Approaches for Description of the Topochemistry of Macromolecular Metal Complexes

摘要

The topochemistry of the distribution of metal complexes on macromolecule ligands is studied on an example of macrocomplexes obtained by the interaction of transition metal compounds (MX_n) with functional groups of the grafted layer (PE-gr-polyallylamine, PE-gr-polyacrylic acid, PE-gr-poly-4-vinylpyridine, etc.). Three main types of macrocomplexes are found out: Ⅰ- isolated complexes ( r ≥ 15 A); Ⅱ -the aggregations of cluster types (complexes of paramagnetic metals unbounded chemically between each other) ( r ≤ 7A). Ⅲ - clusters with a strong exchange interaction (exchange-bound clusters caused by chemical bonds of complexes similar to polynuclear complexes). The ratio and distances between complexes of differen types as well as their possible role in catalytic processes are estimated and discussed.
