| Abstract: | Phosphorus(V) chloride and bromide complexes containing single-halide anions are surveyed in terms of characteristic phosphonium ion Raman shift patterns. Methods of preparation of Phase III phosphorus pentachloride are reviewed and some modes of formation proposed. The nature of the phosphonium cation-single-halide anion interaction is discussed on the basis of observed Raman shifts. With trihalide anions, similar shifts are observed but are strongly dependent on anion symmetry. |
