Sažetak
The development of novel synthetic routes to achieve polyoxometalate (POM) architectures is an attractive research field because POMs are, among others, materials with catalytic, magnetic, bioactive, and energy storage properties. There are two ways of functionalizing inorganic-organic hybrid POMs, one being by the formation of polyoxometalate salt with organic or metal-organic cation and the other one by the substitution of the oxo atoms [1, 2]. Bearing in mind previously stated facts, the tendency of dioxobis(pentane-2, 4- dionato)molybdenum(VI) towards hydrolysis in wet acetonitrile solutions, as well as the solubility of hydrazones [3] we hypothesized the possible formation of hexamolybdate and octamolybdate hybrides functionalised by the hydrazonato complexes. All hybrides were achieved by using aroylhydrazone ligands derived from (iso)nicotinoylhydrazide and differently substituted salicylaldehydes. Structurally diverse POMs with cations of various protonation states were obtained. Characteristic bands in the IR spectra showed facile differentiation of POMs with different nuclearities whereas crystal and molecular structures were unambiguously determined by single-crystal X-ray diffraction.
