| Abstract: | The reaction of the carbodiphosphorane Ph3P=C=PPh3 ( 1 ) with MeI in the presence of iodine gives the oxidation product (IC(PPh3)2)2I[I3]·(I2)2 ( 2 ). In the solid state dimeric units linked by indefinite ···I?···I2···I3?···I2···I?··· chains are found. An additional I···I contact between the cation and the I2 molecule is formed, amounting to 359.23(5) pm. 2 crystallizes in the monoclinic space group P2/c, with the unit cell dimensions a = 2053.9(1), b = 1011.4(1), c = 1889.8(1) pm; β = 105.21(1)° and Z = 4. |
