Diphenyldichlorophosphonium trichloride-chlorine solvate 1 : 1, [PPh2Cl2]Cl-+(3)-center dot Cl-2: An ionic form of diphenyltrichlorophosphorane. Crystal structures of [PPh2Cl2]Cl-+(3)-center dot Cl-2 and [(PPh2Cl2)(+)](2)[InCl5](2-)
An ionic form of diphenyltrichlorophosphorane, namely, diphenyldichlorophosphonium trichloride isolated as a dichlorine solvate (1), was obtained by treating PPh2Cl3 With excess chlorine. The identity of this species was established by single-crystal X-ray analysis and P-31, H-1, and Cl-35 NMR and Raman spectra. Bis(diphenyldichlorophosphonium) pentachloroindate (2) was obtained by the reaction of diphenyltrichlorophosphorane with indium trichloride in dichloromethane for comparison purposes. Its identity was determined by P-31 NMR spectra and single-crystal X-ray analysis.
