Potassium tetrachloroplatinate(II)

Potassium tetrachloroplatinate(II) is a ruby-red crystalline solid and can be prepared by reacting potassium hexachloroplatinate(IV) with cuprous chloride. It is mainly used as a reagent and inorganic catalyst in various chemical reactions. Its application includes the synthesis of other platinum compounds, organic transformations, and electroplating of metals. It is also a potential antitumor agent.

Potassium tetrachloroplatinate(II) can be used as:

• A precursor to synthesize CO-tolerant catalyst for hydrogen-air fuel cells.
• An active and stable catalyst for selective methane oxidation.
• As a starting material to synthesize high-performance Pt-based phosphorescent materials for electroluminescent devices.

Reacts with bis(dithiolates) to form metal-bis(dithiolates) with applications in laser Q-switch materials, liquid crystals, optical CD recording media, bar code materials and superconductivity. Reacts with capping polymers to form shape-control colloidal platinum nanoparticles for catalysis and photocatalysts.
