The vibrational spectrum of methyltetrachlorophosphorus(V)

Abstract

The infrared and Raman spectrum of MePCl₄ in the solid state and in solution in non-ionising solvents is reported. The results suggest the formulation MePCl₃⁺Cl^– in the solid state, while in non-ionising solvents the compound is monomeric with probable C_2v symmetry. The solid-state infrared spectrum of the compound MePCl₄,SbCl₅ is recorded and compared with the corresponding spectrum in acetonitrile. The preparation of Bu^tPCl₄ is reported. Unfortunately this compound decomposed in non-ionising solvents so that steric effects of the t-butyl group could not be examined.
