Neutral chelates of 3,4-diphenyl-5-mercapto-l,2,4-triazole (DPMTH) with Fe(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) have been prepared and characterized by analytical and physicochemical techniques such as magnetic susceptibility measurements, TGA, electronic ESR and IR spectral studies. The IR data suggest that DPMTH behaves as a uninegative bidentate ligand in all the complexes except Fe(II) and Ni(II) where it is tridentate. The complexes have been found to display significant antifugal activity againstA. ahernata andA. flavus.
