reveals structures in solution and Pt–ligand bond strength. The thermal stability in organic solvents, the electrochemical stability, and the reactivity of the complexes in organic or aquatic (water-containing) solution toward the physiologically relevant species glutathione, chloride, and protons was tested, revealing remarkable stability or inertness of the complexes.
