PCls is added portionwise with vigorous stirring to liquid NH3 at -70 'C. An almost clear solution is obtained which yields a white powder when the NH3 is evaporated off. The weight of the final precipitate reveals that 8 moles of NH3 have been taken up for each mole of PCI5. The product is kept at
