Abstract:


The review covers structures and properties of compounds, possessing porous crystal lattices, or coordination polymers, which are assembled on the basis of polynuclear oximate or hydroxamate complexes of 3d metals. It is shown that magnetic properties of such systems are governed by the exchange interactions in the polynuclear building blocks and can be pre-determined by the appropriate choice of starting compound. In contrast, the structure and topology of the framework, obtained on the basis of polynuclear oximate or hydroxamate, do not correlate with the quantity of vacancies in coordination spheres of metal ions in the starting compound, as well as they do not correlate with the quantity of ligand donor atoms. Some of the compounds, considered in this review, show ability to absorb different substrates. Such absorption is different from "classical" filling of micropores; sorption capacity is governed by the energy of host-guest interactions rather than the volume of rigid micropores in crystal lattice.
