Abstract: Significance of transition metals in industries and biological systems, in general, and iron, in particular is very well established. But the application of these metals in the form of aqueous solutions in medicinal field is limited as they are highly toxic. In such cases polymer-metal complexes can be thought of better substitutes for introducing the metal ions into a biological system. When a non-toxic, water soluble and biologically compatible polymer like poly(vinyl pyrrolidone) is used as a ligand, the spectrum of applications of such complexes gets broadened. Poly(vinyl pyrrolidone) – Iron (II) complexes were prepared using aqueous solutions of PVP (30K) and ferrous sulphate heptahydrate at room temperature with varied molar compositions. Solid polymer-metal complexes were obtained by evaporating the solvent. The prepared complexes were characterized by FTIR, 1H-NMR with DMSO as solvent and 13C-NMR. The extent of complex formation was predicted by comparing the spectral data of the complexes with those of pure PVP. Crystalline property of the complex was studied by Differential Scanning Calorimetry (DSC) and for magnetic property by Vibrating Sample Magnetometry (VSM). Antimicrobial activity of the complex was also studied by Agar Well Diffusion method.

Index Terms – Polymer-metal complexes, poly(vinyl pyrrolidone), transition metals.
