Spectroscopic and electrochemical investigations and antibacterial activity of binuclear Pd(II) and Pt(IV) complexes of newly synthesized tridentate heterocyclic compounds Hegazy, Wael Hussein Antibiotics Pd(II) complexes Pt(IV) complexes Binuclear complexes Spectroscopic studies Heterocyclic Schiff bases 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. Atlanta Publishing House LLC 2014-09-30 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf https://www.eurjchem.com/index.php/eurjchem/article/view/1045 10.5155/eurjchem.5.3.415-418.1045 European Journal of Chemistry; Vol. 5 No. 3 (2014): September 2014; 415-418 2153-2257 2153-2249 eng https://www.eurjchem.com/index.php/eurjchem/article/view/1045/pdf_1045
