Structure and reactivity of metal compounds
Laboratory of coordination compounds conducts research which concerns the coordination compounds of s-, p-, d-, f-metal carboxylates and diketonates with specified dimensionality: frameworks, layered and linear polymers, mononuclear compounds. Deliberate construction of these architectures allows obtaining the complexes with specified features needed for the compounds either to exhibit functional properties or to be used as precursors for inorganic functional materials.
Volatile complexes are used as precursors for Metal-Organic Chemical Vapor Deposition (MOCVD) of superconductive and optical oxide materials. Compounds that could undergo hydrolysis in solution are used as precursors for Metal-Organic Chemical Solution Deposition for oxide and fluoride materials.
Special attention of the laboratory is drawn to the coordination chemistry of precursors. For the synthesis of unstable compounds with a tendency to hydrolysis or to solvent departure, we use Schlenk apparatus equipped with vacuum and dry argon lines.
Study of crystal structures is performed by means of single crystal and powder X-ray diffraction; the composition and properties are studied by a variety of physicochemical methods of the compound characterization (NMR, IR, TG-DTG, EDX, mass spectrometry).
A part of research work is devoted to mixed-metal 3d and 4f supramolecular compounds and rare earth coordination compounds based on oxo/hydroxo metal clusters as promising precursors for metal-organic frameworks.
