The Isolation from Diethyl Ether of Ionic <(Me2N)3PI>I and <(CH2=CHCH2)2PhPI>I, and the Crystallographically Characterised Molecular ‘Spoke’ Structure PhMe2PI2
Ten new compouds of stoichiometry R3PI2 have been prepared by the direct reaction of PR3 and I2 in diethyl ether solution.The compounds have been characterised by Raman and solid-state 31P- magic angle spinning (MAS) and solution NMR spectroscopy.Solid-state 31P- MAS NMR studies indicate that the predominant solid-state species is the molecular ‘spoke’ structure R3P-I-I; however, in some cases a minor peak was also assignable to the ionic species, I.Additionally, solid-state 31P- MAS NMR studies of (Me2N)3PI2 and (CH2=CHCH2)2PhPI2 indicate that, in contrast to all other compounds of stoichiometry R3PI2 prepared in diethyl ether, they are exclusively ionic, I.The crystal structure of PhMe2PI2 shows it to have the molecular ‘spoke’ geometry, PhMe2P-I-I, d(I-I) = 3.408 Angstroem, previously observed for Ph3PI2, in agreement with solid-state 31P- MAS NMR results.
