Some new zinc pseudohalidebis-imine complexes: Synthesis,characterization, thermokinetic decomposition study and antimicrobialproperties

Nowadays synthesis of new ligands suitable and then preparation of their complexes are inthe frontier in pure and applied inorganic chemistry. Accordingly, the iminic ligands areimportant, which can be coordinated to metal ions via thier iminic nitrogen atoms to form therelated imine complexes. These complexes are applicable in catalytic, industrial andmedicinal(as antibacterial, anti fungal and antioxidant agents) fields in recent years]۱-۴[.Iminecomplexes have also cytotoxicity effects aginst varios cancerious cell lines. Recently also thesecomplexes are appliedas precursor to prepare nano-structured metal oxides. Among variousmetal oxides that were studied, zinc oxide nanoparticlesare of great interestdue to variousapplications in optic and biological properties.In this work, a new bidentate bis-imine ligand obtained from ۲-methoxyphenyl-۲-propenaland phenylenediamineand its four coordinated Zn(II) pseudohalidecomplexes(inwhichpseudohalide is SCN-, N۳- and NO۳-) have been synthesized and investigated by analytical andspectral data(FT/IR, UV-Visible and ۱H and ۱۳C NMR) and thermal analyses. Moreoverantibacterial and antifungal properties of the ligand and its complexes were evaluated by welldiffusion method. Finally the zinc complexes were used as precursor for preparation ofnanostructured ZnO.
