| Vanadium is one of the necessary trace elements in the life. The inorganic salt of vanadiumand The complexes of vanadium both have good biological and pharmacological activity,Thekey performance in such aspects as to the hypoglyemic lipid-lowering effect of insulin and soon. If Vanadium and organic ligand chela synthetic complexes, the toxicity will be greatlyreduced.At the same time as acylhydrazone base,containing N, O and some other donor atomsusually has the character ability, which can more easily coordinate with transition metal ionsand form various coordination geometry.This kind of compounds have good biologicalactivity and have good biological activity which led many people to pay widely attention inmany fields,such as analysis,catalysis,medicine,magnetic and other fields.Above.they have awide range of applications.In this paper,22new vanadium metal hydrazone complexes weredesigened and synthesized on the basis of reading a lot of literatures.And bring in methylmaltol,ethyl maltol,8-hydroxyquinoline, acetohydroxamic acid and so forth auxiliaryligand. And the structures of these complexes are analyzed.The thesis mainly is divided into three parts：1)20mixed ligand was synthesized acyl hydrazone vanadium complexes，and for theX-ray single crystal diffraction, infrared spectra, UV-Vis spectra, thermogravimetric-determination of the differential thermal analysis, etc.2) A synthesized salicylic aldehyde schiff base ligands vanadium complexes，and for theX-ray single crystal diffraction, infrared spectra, UV-Vis spectra, thermogravimetric-determination of the differential thermal analysis, etc.3) one of Kojic acid was synthesized adjacent phenanthroline vanadium mixed ligandcomplex，and for the X-ray single crystal diffraction, infrared spectra,UV-Vis spectra,thermogravimetric-determination of the differential thermal analysis, etc. |
