文摘
A number of gold(III) complexes containing tetradentate Schiff base ligands have been synthesized andcharacterized. Gold(III) forms four-coordinate square planar complexes with these ligands. These complexes havebeen characterized by their elemental analyses and UV-visible, infrared, NMR, and mass spectra. Preliminaryradiochemical studies with Au-198 show that these complexes are also formed at the tracer level from (Bu4N)-[198AuCl4].
