4DescriptionAbstract Copper(II), cobalt(II), nickel(II) and zinc(II) complexes of 5-chloroisatin Schiff base (L) (L= Schiff base derived from 5-chloroisatin and 2-methyl-4- nitro aniline) were synthesized and characterized. The authenticity of the ligand and its metal complexes had been established by micro analysis, IR, NMR, LC/MS, UV-Vis and electrical conductance measurements. The ligand acts as a bidentate in which the carbonyl oxygen and the azomethine nitrogen of 5-chloroisatin are involved in co-ordination. Square planar geometry was proposed for Cu(II) and Ni(II) complexes and tetrahedral geometry was proposed for Co(II) and Zn(II) complexes. The ligand and its metal complexes have been screened for their antibacterial activity against bacterias viz. Staphylococcus aureus and Escherichia coli etc. and antifungal activity against fungi Aspergillus niger and Aspergillus flavous etc. The activities of both the samples have shown significant and noticeable changes on complexations.
