A variety of R3PI4 compounds have been synthesized and characterised by elemental analysis, NMR and visible spectroscopy. Apart from Ph3PI4, all are reported for the first time. X-Ray crystallographic studies on
Reaction of Iodine with Triphenylphosphine and Tiphenylarsine

The reaction of PPh3 with I2 leads to disproportionation of iodine and formation of (PPh3I)+ and I3-.Dichloroethane solutions of these give I3 (I) while toluene solutions give (PPh3I)I3 (2).Both compounds were structurall
Determination of Equilibrium Constant of Intimate and Solvent-separated Ion-pair Equilibria

A method, based on refractometric and conductometric measurements, has been developed for calculating equilibrium constant (K) and solvation number (n) of the two distinct species of intimate and solvent-separated ion-pair coexisting in equilibrium: A(+), B(-) + nS A(+)//B(-).This method has been applied to the system: Ph3M(+), I3(-) + nTHF Ph3M(+)//I3(-) (where M = N, P, As or Sb).It is found that a single THF molecule intercalates between cation and the anion.
