dipotassium tetrachloroplatinate

Potassium tetrachloroplatinate solution is used in the preparation of platinum (Pt) nanoparticles. Ligands like ammonia or triphenyl phosphine can able to replace the chloride ligands to afford various derivatives. The replacement by ammonia results in the preparation of cisplatin, which is used in the cancer treatment. Further, it is used as catalyst in the hydroarylation reaction.

Potassium tetrachloroplatinate(II) is a ruby red crystalline solid and can be prepared by reacting potassium hexachloroplatinate (IV) with cuprous chloride.

Human poison by ingestion. Poison experimentally by intraperitoneal route. Corrosive to human skin by intradermal route. Mutation data reported. Human systemic effects: eosinophha, gastritis, renal function tests depressed. When heated to decomposition it emits toxic fumes of Cland K2O. Used as a catalyst for hydroformulations, photocatalysts, and dissociation of water. See also PLATINUM COMPOUNDS.

It forms crystals from aqueous 0.75M HCl (20mL/g) between 100o and 0o. Wash them with ice-cold water and dry.
