popup.description1
Theoretical substantiation of polycondensation processes in solutions of polyoxometalate anions in the presence of cations of d- and f-metals as a basis for purposeful synthesis of crystalline salts with these cations, development of conditions for "green" synthesis of new "pure" inorganic polyoxometalates and organo-inorganic hybrids, study of the crystal structure of polyoxometalates with cations of d- and f-metals, elucidation of the periodicity of changes in the characteristics of Ln-POM salts, search for useful properties (magnetic, catalytic) of synthesized salts. Determination of substitution limits and phase stability regions of solid solutions in lanthanide orthoarsenate and ortovanadate systems; supplementing the state diagrams of the above systems and replenishing the created 3d-database of isomorphous substitutions.

Theoretical justification of polycondensation processes in solutions of polyoxometalate anions in the presence of d- and f-metal cations as a basis for the targeted synthesis of crystalline salts containing these cations; development of “green” synthesis conditions for new purely inorganic polyoxometalates and organic–inorganic hybrids; investigation of the crystal structures of polyoxometalates with d- and f-metal cations; elucidation of periodic trends in the properties of Ln–POM salts; and exploration of useful properties (e.g., magnetic and catalytic) of the synthesized salts. Determination of substitution limits and phase stability regions of solid solutions in the La1–xLnxAsO4, Sc1–xLnxAsO4, Gd1–xLnxAsO4, Tb1–хLnхAsO4, Lu1–xLnxAsO4, and Ln1–xLn’xVO4 systems; contribution to the phase diagrams of these systems and expansion of the developed 3D database of isomorphous substitutions.
