Potassium Palladocyanide, K₂Pd(CN)₄

Potassium Palladocyanide, K₂Pd(CN)₄.3H₂O, which crystallises on evaporation of the solution. Soluble in water and alcohol, it effloresces in air, and at 100° C. loses two molecules of water, yielding the mono-hydrate, K₂Pd(CN)₄.H₂O. At 200° C. it becomes 'anhydrous. It is isomorphous with the corresponding platino-cyanide.
