Synthesis, Characterization And Biological Activity Of Transition Metal Complexes With Salicylaldehyde Schiff Bases And Hydrazone

Formaldehyde and ammonia can be condensed to a kind of base. That is often namedSchiff-base, because Mr Schiff found that. It is easy to coordinate with transition matelions because two or more coordination atoms are contained. A series of differentperformance complexes can be synthesized by changing raw material. Salicyaldehydeschiff base and hydrazone transition metal complexes have unique properties, and bewidely used.Urease inhibitors inhabit urine activity directly or indirectly. Schiff base and itscomplexes have better biological activity, containing inhibiting urease activity, and beapplied in the field of agriculture, animal husbandry, and environmental protection, etc.It is a hot spot of being concerned.This article mainly divides into four parts:1) Eight multi-core and di-nuclear Schiff base complexes are synthesized, mainly includ-ing Cu(II), Cd(II) metal polynuclear complexes and five Fe(III), V(II), Zn(II) metaldinuclear complexes. Tests characterized by X-ray single crystal diffraction, IRspectros-copy, thermal analysis, etc.2) Ten mononuclear Schiff base complexes are synthesized. Tests characterized by X-raysingle crystal diffraction, IR spectroscopy, thermal analysis, molar conductivity, etc.3) Four single-core V(IV) and Mo(IV) hydrazone complexes are synthesized. Testscharacterized by X-ray single crystal diffraction, IR spectroscopy, molar conductivity, etc.4) Test and analysis the inhibiting urease inhibitor of some complexes.
