Abstract

The mixed ligand complexes of Cu(II), Zn(II) and Hg(II) were prepared using 4-aminoantipyrine (4-AAP) and thiocynate ions with microwave irradiation. The prepared complexes were characterized by elemental analysis, conductance measurement, UV-Visible, FT-IR and NMR spectral analysis. The conductivity measurements reveal that the complexes are nonelectrolyte. The elemental analysis showed the formation of 1:2 (metal: ligand) complexes with coordination number 4.The formulae of the complexes are [Cu(AAP)2(SCN)2], [Zn(AAP)2(SCN)2] and [Hg(AAP)2(SCN)2]. The antimicrobial and antifungal activities of the complexes were tested with various microorganisms by disc diffusion method. The antimicrobial results indicate that the metal complexes are moderately active compared to the ligand, 4-aminoantipyrine.
