Abstract

New Pd(II) and Pt(IV) binuclear complexes with two heterocyclic Schiff base ligands of type ONO derived from condensation of salicylaldehyde with 4-aminoantipyrine have been synthesized and characterized using elemental analysis, IR, electronic absorption spectra, magnetic moments. It has been found that the stoichiometric ratio is metal:ligand (2:2) with Pd(II) or Pt(IV) ions forming binuclear complexes. The electrochemistry of the Pt complexes for Pt(IV)/Pt(II) redox couple was investigated by cyclic voltammetry. According to molar conductance, the complexes may be formulated as [Pd2(L1)2], [Pt2(L1)2(H2O)4]Cl2, [Pd2(L2)2]Cl, and [Pt2(L2)2(H2O)4]Cl3. On the basis of the magnetic moments, square planar geometry is suggested for Pd(II) complexes and octahedral geometry is suggested for Pt(IV) complexes. The antibacterial activity of the ligands and complexes were assessed against Gram‐positive bacteria B. subtilis and S. aureus and Gram‐negative bacteria S. typhi and Salmonella spp.
