The changes of ³¹P nuclear magnetic resonance spectra of P₂I₄-CS₂ solutions and of molecular weights of P₂I₄ in benzene with time have shown that in inert solvents a gradual disproportionation occurs with formation of PI₃. White Phosphorus, P₄, is not formed by this process. Instead the initially formed disproportionation product with higher Phosphorus content changes into a polymeric solid PnI by cleavage of PI₃, which accounts for the increasing displacement of disproportionation equilibrium. The UV spectrum of P₂I₄ in n-Hexan is reported. The molar extinction coefficients indicate a considerable delocalization of unshared electron pairs of the Phosphorus atoms.
