Question:
During a halogen / halide displacement reaction demo, our lecturer reminisced about his time at school when he used to synthesize tri-nitrogen iodide using I2 and an organic compound. After looking into this, I thought that he had mixed up nitrogen tri iodide with this tri nitrogen iodide [(I-N=N-N-I2)?] which he speaks of. This would be very unstable, and another lecturer at the university also thinks that he has it confused. I would be very interested to hear your thoughts on this matter, and the identity of this mystery organic compound. (please do not post this as it is very dangerous, someone in the US lost a foot playing with NI3, and if tri nitrogen iodide is as unstable as I think, it may be more than a foot that someone loses)


Replies:
Roger,

This kind of error pops up frequently whenever one is not careful about chemical nomenclature. Your lecturer was careless in his presentation. The compound in question is, as you correctly suspected, nitrogen tri-iodide (NI3).

Regards,
ProfHoff
