Synthesis, Characterization and Role of Anions (Nitrate, Sulphate, Oxalate and Acetate) \in the Biological Activity of Hydrazine Derived Compounds and Their Metal Chelates

摘要

Hydrazine derived compounds and its Co(II), Cu(II) and Ni(II) chelates having the same metal ion but different anions (e.g., nitrate, sulphate, oxalate and acetate) have been synthesised andcharacterised by their physical, spectral and analytical data. In order to evaluate the participating role of anions in the antibacterial activity, these synthesised ligands and its metal chelates have beenscreened against bacterial species such as Staphylococcus aureous, pseudomonas aeruginosa, Klebsiella pneumonae and Proteus vulgarus, and the results are reported.
