In present research, various ligands are planned from commercially available chemicals. Treatment of substituted benzonitriles with hydroxylamine hydrochloride in the presence of sodium carbonate using ethanol / methanol as solvents will furnish N-hydroxybenzamidines in good yields. Upon further treatment of N-hydroxybenzamidines with various transitions metals under appropriate reaction conditions, a library of target metal complexes was obtained in good yields. After getting encouraging results from metal complexation of benzamidines, another type of organic ligand for example chalcone will also considered to prepare diverse range of metal complexes. For this purpose, various substituted chalcones were formed by treating different acetophenone with suitable benzaldehydes under mild and basic reaction conditions. Furthermore, reaction of various metal (II) chlorides / nitrates with various analogues of chalcones under reflux reaction conditions will provide new metal complexes in good yields. Finally, detailed chemical structures of synthesized compounds were characterized through spectroscopic methods such as FTIR, ¹H NMR and ¹³C NMR spectroscopy. Their role in paint will be studied as a antibacterial materials.
