Nitrogen triiodide is an inorganic compound with the formula N I₃. It is an extremely sensitive contact explosive: small quantities explode with a loud, sharp snap when touched even lightly, releasing a purple cloud of iodine vapor; it can even be detonated by alpha radiation. NI₃ has a complex structural chemistry that is difficult to study because of the instability of the derivatives.
