message: Previously the article listed the two as synonymous, however aren't they NI3 and NH4I3 respectively?  If they are the same, an explanation is in order in the article somewhere.  For now I've removed "ammonium triiodide" from the opening paragraph.  If someone puts it back can they please an an explanation as to why they are the same? 129.82.48.50 23:08, 16 May 2006 (UTC)
thread_title:  Nitrogen triiodide really the same thing as ammonium triiodide? 

message: A small error on the stability of the compound.  It is not due to the stability of the products.  That has nothing to do with the activation energy of NI3.  The instability of NI3 is mainly due to the relative sizes of the Nitrogen and the Iodine.  Since the Iodine atoms are huge in size compared to the Nitrogen atom, they are packed close together.  This causes high repulsive forces between the 3 Iodine atoms, causing instability of the molecule.  —Preceding unsigned comment added by 75.46.109.190 (talk) 22:24, 21 October 2007 (UTC)
replies: text: That is an insightful proposal, or at least helpful to me because you are separating the kinetics from the thermodynamics. But it is your theory might not be admissable (Wikipedia:No original research). As indicated by Marcus theory (the article is in rough shape), the activation energy is coupled to the thermodynamic driving force. --Smokefoot 22:35, 21 October 2007 (UTC)
replies: text: I think there might be some merit to the idea that the instability of the compound is due to steric repulsion. However, we would need a reference we can cite, and I haven't been able to find any. Has anyone studied the mechanism of decomposition in detail? There are other possible explanations, for example, that the compound is unstable because of the weak N-I bond, due to the poor overlap between atoms that are so different in size. --Itub 12:33, 22 October 2007 (UTC)
thread_title: Error on the reason for instability of NI3 

message: "Gunpowder like snap". WTF? Gunpowder does not detonate and thus does not give a snap like this substance does. Where does that line come from? I find it somewhat inaccurate.  — Preceding unsigned comment added by 93.162.119.14 (talk) 06:46, 7 June 2012 (UTC)
thread_title: Introduction

message: Which thermodynamical dimension is this? Is it the reaction's enthalpy ΔH or the reaction's free enthalpy ΔG? If it is ΔRH, the value is a bit strange because it is less than the ΔRH of the equivalent reaction with NCl3 (ca. -460 kJ/mol), implying that the thermal decomposition of NCl3 is more violent (even if it occurs at higher temperature due to higher kinetic stability) than that of NI3. As far as described in the articles, the opposite should be the case... --79.243.242.143 (talk) 20:51, 6 September 2013 (UTC)
replies: text: In accordance with the German wiki "Stickstoffhalogenide", 290 kJ/mol is the enthalpy of formation (ΔfH) for NI3, that means -290 kJ/mol is the decomposition reaction's enthalpy for one molecule of NI3. That is also what I expected most. So the reaction enthalpy for the reaction given in the text must be -580 kJ/mol, since there are two molecules of NI3 decomposing. I only don't know where the value is taken from in the German article, because that article also cites no sources for the ΔfH of NI3 being +290 kJ/mol. So that should better be checked before the value in this article is corrected... --79.243.233.89 (talk) 15:33, 13 September 2013 (UTC)

replies: text: "Heaviest gas" has no meaning that I can think of.  Sublimation is not abrupt and there is no characteristic Tsub.  My 2 cents.--Smokefoot (talk) 11:55, 13 December 2018 (UTC)
thread_title:  Is this the heaviest gas? 

message: Youtube is full of videos showing an explosion and purple cloud. This article should say whether that purple cloud is toxic.
The first paragraph of this article says "...releasing a purple cloud of iodine vapor", but later the article says
"The dry material is a contact explosive, decomposing approximately as follows:
8 NI3 · NH3 → 5 N2 + 6 NH4I + 9 I2"
So which is it? "Iodine vapor"? Or is the purple cloud a combination of Ammonia, Ammonium iodide, and Elemental Iodine (I2)? And is the purple cloud an actual vapor or is it a cloud of solid (liquid?) Iodine particles? Iodine boils at 113.7 °C and Ammonium iodide boils at 551 °C so (based upon my extensive education (which consists of getting a C- in high-school chemistry) it seems that only the Ammonia would be a vapor, while the purple stuff would be an aerosol.
Could someone who understands chemistry please write up a paragraph with citations explaining what is in that purple cloud and whether it is toxic? 2600:1700:D0A0:21B0:5A9:3B45:A28C:DE50 (talk) 18:40, 4 April 2022 (UTC)

message: Nitrogen Triiodide is sometimes referred by the name "Touch Powder", I feel like it should at least be mentioned or added as a name. Tungster24 (talk) 23:02, 9 July 2022 (UTC)
thread_title:  Touch Powder as a name? 

message: AsI know from  producing
histcompound when an A level student, it is stable enough to be easily transported when wet with water or alcohol. In fact even when damp with either liquid, if a flame is applied, it decomposes with the described iodine cloud, but not explosively. Once left to dry, a fly landing on it causes it to explode. 92.18.253.83 (talk) 14:03, 23 April 2023 (UTC)
