In an effort to develop novel gold-based chemotherapies, gold (III) coordination complexes possessing a series of di-2-pyridyl ligands were targeted as synthetic products. It was found that di-2-pyridyl ligands linked by different groups exhibited varying coordination to gold (III). Di-2-pyridyl sulfide (DPS) exhibited bidentate binding to gold (III), and formed a complex ion with a gold tetrachloride counter ion {[(DPS) AuCl2] AuCl4; compound 3}; di-2-pyridyl ...
