An X-ray crystallographic study of the reagent Ph₃PCl₂ reveals it to be [Ph₃PCl⁺...Cl^-... ⁺ClPPh₃]Cl and not trigonal bipyramidal, molecular charge-transfer Ph₃P-Cl-Cl or the simple ionic species [Ph₃PCl]Cl; this contrasts with the conclusions from all previous spectroscopic data recorded on compounds of stoichiometry R₃PCl₂ by earlier workers, and represents the first compound of this formula to be crystallographically characterised.
