Hybrid organic-inorganic compounds based on the Lindqvist polyoxomolybdate and dioxomolybdenum(VI) complexes

Organic-inorganic hybrids, based on the Lindqvist-type polyoxometalate (POM) and dioxomolybdenum(VI) complexes, have been synthesized by hydrolysis of [MoO2(acac)2] (acac = acetylacetonate) in the presence of aroylhydrazone ligands in weak donor solvents. This provides an efficient route to materials that contain open coordination sites or sites occupied by labile ligands. Removal upon grinding or heating of the labile acetonitrile and acetone molecules on the dioxomolybdenum centres and the reaction in the solid-state represents a way for designing structures with the Lindqvist Mo6O192- anion coordinated to the metal centres of two complex cations. The compounds were characterised by the single crystal and powder X-ray diffraction methods, elemental analysis, IR spectroscopy, TG and DSC analyses.
