Mechnikov National University popup.description2 First the kinetics of ozone low-temperature decomposition by aerosil-immobilized oxyaldiminopropyles L/Si as well as by their complexes with Cu(II), Co(II) and Mn(II) at different ratios of initial ozone concentration, immobilized ligands content and complexes has been studied. It has been showed complexes ML2/Si activity in ozone decomposition reaction to be determined by central atom and ligands nature as well as coordination center geometry. The activity of complexes decreases during reaction and doesn't reduce after ozone-air mix cut as a result of irreversible change of complex composition dew to ligands oxidative destruction. At that Cu(II) and Co(II) don't change oxidation number to the reaction end. The compounds with 4-phenylthiosemicarbazide of common composition MLnX2 and 3d-metals phthalates, tartrates and salicylates complexes with nicotinamide have been synthesized in aqueous medium.With the help of IR spectroscopy method the outer-sphere character of nitrate, sulfate and all carboxylate with the exception of oxalate ions has been confirmed and it has been stated nicotinamide to be coordinated to metals as monodentate through pyridine ring nitrogen atom while thiosemicarbazide is bidentate coordinated through sulfur and nitrogen atoms. For 3d-metals nicotinamide-phthalate compounds thermostability series depending on metal ion agreeing fully with such series obtained earlier for similar valerate and benzoate complexes have been stated. It has been stated the composition of 3d-metal tartrates coordination compounds with nicotinamide and thiosemicarbazide to be determined by metal nature not depending on reagents ratio.
