Coordination compounds of the transition metals find their use in almost every field of human life. In the proposed work we have selected a copper salt for complexing with poly(vinylpyrrolidone) ligand. Copper compounds are used as bacteriostatic substances, fungicides and food preservatives. Poly(vinylpyrrolidone) is a water soluble polymer having many eco-friendly uses which are the results of its unique properties like low toxicity, biological compatibility, inert behavior towards many compounds, complexing ability, resistant to thermal degradation and film forming ability. Keeping these properties of copper and poly(vinylpyrrolidone) in view and with the objective of synthesizing more environment friendly compounds, complexes of poly(vinylpyrrolidone) and copper were prepared by using aqueous solution of PVP(30K) and alcoholic solution of hydrated copper chloride at room temperature with different molar composition. Crystalline polymer-metal complexes were obtained by evaporation of the solvent. They were characterized by solubility studies, CHN analysis, FTIR, H-NMR and 13C-NMR. Procedure was repeated with aqueous solution of the salt also. The spectral analysis of the reactants and the complexes confirmed the formation of expected complexes. The conditions for better complexation were optimized. Copyright@ International Science Community Association
