Boron Triiodide
This compound is nitrogen triiodide.
Iodine (I2) reacts with iodide (I-) to form triiodide ion (I3-). Although I2 is insoluble in water, I3-is very soluble, so adding KI will pull I2into solution is I3-.

I3- is known as the triiodide ion (or sometimes tri-iodide ion, for better readability). It arises in equilibrium when elemental iodine (I2) and the iodide ion (I-) are both present.
Iodine is added to a solution of white phosphorus in carbon disulfide as solvent to form phosphorus triiodide. P4 + 6I2 → 4PI3
The chemical formula of nitrogen triiodide is NI3.
Iodine crystals and concentrated ammonium hydroxide solution.3I2+4NH4OH = NI3+3NH4I+4H2OAmmonium iodide is filtered out and the precipitate on the filter paper is put in a ammonium hydroxide solution. Take out and dry before detonation.SAFTEY!!The Whole Production MUST BE DONE UNDER A FUME HOOD!! THE FUMES FROM THIS PROCESS ARE FATAL!!Do NOT GET NITROGEN TRIIODIDE ON YOUR CLOTHES IT STAINS ANYTHING IT TOUCHES.WEAR EARPLUGS WHEN DETONATING THE TRIIODIDE AND KEEP A FAIR DISTANCE! SHRAPNEL FLIES!!
Boron Triiodide
The chemical formula for nitrogen triiodide is NI3. It contains:1 Nitrogen atom3 Iodine atomsIn brief, nitrogen triiodide is purple in colour and extremely reactive.
Phosphorus triiodide reacts violently with water, so the reaction is exothermic. If a large amount of phosphorus triiodide is mixed, an explosion will most likely occur. If it is a small amount, then it will be similar to the reaction of potassium with water.

It would be phosphorus (I) iodide. However, this is not a stable compound; under normal conditions phosphorus and iodine combine to produce phosphorus (III) iodide (which is also not stable ... it's explosive ... but is considerably more stable than phosphorus (I) iodide is). The electron configuration of the phosphorus in PI3 is [Ne]s2, while that of PI is [Ne]s2p2. The filled s subshell is at least metastable, while a filled s subshell plus a partially filled p subshell is normally not and requires considerable effort to maintain.
