) was the first major inorganic anticancer drug. It works by binding to DNA, cross-linking the strands and preventing replication. Ruthenium and Iridium complexes (like

ions act as complexing agents to stabilize the metal in solution as 3. Coordination Chemistry and Catalysis Chemistry of Precious Metals

Precious metals display a wide variety of oxidation states, though they generally prefer low-spin configurations: Predominantly +1positive 1 . It forms linear complexes like Gold (Au): Commonly +1positive 1 +3positive 3 typically adopts a square planar geometry. ) was the first major inorganic anticancer drug

Most are insoluble in standard acids. Gold and platinum require Aqua Regia (a 3:1 mixture of HClcap H cap C l HNO3cap H cap N cap O sub 3 HNO3cap H cap N cap O sub 3 acts as an oxidant, while the Cl−cap C l raised to the negative power Gold and platinum require Aqua Regia (a 3:1

). This means they prefer to remain in their metallic (0) state rather than forming ions.
