A series of four new Pd(II), [Ni(II)dppm], [Cu(II)bipy] and [Cu(II)phen] complexes of 2,4-dihydroxybenzaldehyde-4- phenyl-3-thiosemicarbazone (DHBPTSC). The DHBPTSC (ligand) and complexes were established by using means of IR, 1H NMR, Mass, electronic, EPR spectra and elemental analysis discussed. The FT-IR spectral data intimate the coordination of sulphur and azomethine nitrogen with the central metal ion. The EPR spectra of absorbance were observed for Cu(II)bipy and Cu(II)phen complexes the g values g‖ = 2.126 and g‖ = 2.108, respectively. The g values are found in both the complexes had suggested elongated tetragonal geometry for the molecules. These compounds were further tested with antibacterial, antifungal and antioxidant activities.
