Synthesis, characterization and antimicrobial properties of lipophilic palladium complexes bearing iminopyridine ligands

Abstract

The reaction of [PdCl22-coe)]2 (coe = cis-cyclooctene) with nine lipophilic iminopyridine ligands (NN′, 1ai) afforded the corresponding metal complexes cis-[PdCl2(NN′)] (2ai) with concomitant loss of the labile coe ligands. All iminopyridine complexes were characterized by physicochemical and spectroscopic methods. The molecular structures of two complexes, 2a and 2b, were determined by single crystal X-ray diffraction studies. All complexes were tested for their potential antifungal and antibacterial activities.
