2. Red crystalline [NiCl,(PPh,CH,Ph)2] is diamagnetic. On heating to 387 K for 2 hours, a blue- green form of the complex is obtained, which has a magnetic moment of 3.18uB at 295 K. Suggest an explanation for these observations and draw structures for the complexes, commenting on the possible isomers.
