Potassium tetracyanopalladate

Potassium tetracyanopalladate (II) 3H2O [10025-98-6] M 377.4. All operations should be carried out in an efficient fume cupboard - Cyanide is very POISONOUS Dissolve the complex (ca 5g) in a solution of KCN (4g) in H2O (75mL) with warming and stirring and evaporate hot till crystals appear. Cool, filter off the crystals and wash with a few drops of cold H2O. Further concentration of the mother liquors provides more crystals. The complex is recrystallised from H2O as the colourless trihydrate. It effloresces in... [Pg.457]

Potassium tetracyanopalladate(II) when crystallized from water forms the 3-hydrate, which is a white crystalline salt, isomorphous with the corresponding rhombic tetra-cyanoplatinate(II). The 3-hydrate is efflorescent in air it loses two molecules of water of crystallization at 100° and the thii d at 200°. When the compound is heated to moderately high temperatm-es, it decomposes with the formation of palladium, cyanogen, and potassium cyanide. The 1-hydrate is readily soluble in water and in liquid ammonia and is somewhat soluble in alcohol giving colorless solutions in each case. The addition of dilute acids to potassium tetracyanopalladate(II) precipitates pal-ladium(II) cyanide, while boiling with concentrated sulfuric acid completely decomposes the compound. [Pg.246]
