Spectral Studying and Chemical Properties of (Imine and Formazan)-Ligands with Some Complexes With Zinc(Zn2+)

Abstract

Formazan compounds are readily synthesized via the reaction of azo group with anile compound to produce high quantitative yields and high purity. In the last few years, formazan derivatives have been proved to have interesting biological activities., for this reason , series of imine and formazan compounds were synthesized as a ligands , studying optimal conditions for its complexes with zinc ion . Synthesized ligands with two complexes were identified by spectral techniques like ((FT.IR–spectra , ¹H.NMR-spectra , UV.Vis –spectra)) , and physical studies such as (( molar conductance ., polarity effect of series from solvents .,melting point )). The results indicate that the ligands behave as tridentate donor ligands forming chelates with (1:2) (Zn: ligand).
