Synthesis, Characterization and Antibacterial Study of Selected Metal Complexes Derived from Modified of PVA

Abstract

A new ligands(modifier polymers) L₁, L₂, L₃ , L₄ and L₅ were prepared according to method ^[8]  by reaction of polyvinyl alcohol(PVA) withi(acid chloride)[1]a or [2,3]a,b in dimethyl formamide. The Ligands were characterized by (FT-IR), (UV- Vis) and (¹H-NMR) spectra some of them. Synthesis some transition metals complexes of these ligands and described via (FT-IR, UV-Vis) spectra, [Thermo gravimetric analysis (TGA), Differential Scanning Calorimetry (DSC)], (SEM) and antibacterial activity was screened thought two types of bacteria. The octahedral geometrical was suggested for Co⁺², square Planer geometrical was suggested for Ni⁺²and tetrahedral geometrical was suggested for Cd⁺²
