We were able to elucidate completely the mechanism of formation of polymeric phosphorus nitrile chlorides. Phosphorus pentachloride has a well known structure In the vapor state the molecule is in the form of a trigonal bipyramid Pure liquid PC1sub 5 exhibits a Raman spectrum which has been interpreted on the basis of a trigonal bipyramid structure In the crystal however phosphorus pentachloride has ionic struc ture corresponding to PC1sub 4 PC1sub 6 hen phosphorus pentachloride is dissolved in polar solvents, it acts as an electrolyted is present in ionic form Transference number experiments indicate at PClsub 4 and PClsub 6 - are formed when phosphorus pentachloride is dissolved in nitrobenzene We suggested that with ammonia and derivatives of ammonia res ectively phosphorus pentachloride may react as a salt PCl sub 4 PC1sub 6. An ionic mechanism should be especially observed when a polar solvent is employed.
