Talk:Interhalogen

More than two Halogens[edit]

Can you get interhalogen compounds with more that 2 halogens eg brcl3f2 —Preceding unsigned comment added by Monkey sandwich (talk • contribs) 23:25, 11 April 2009 (UTC) <--(moved after template)-->[reply]

I did some Googling a few days back. It appears that there are no neutral ternary interhalogens, but there are ternary interhalogen cations and anions. Lavateraguy (talk) 13:52, 3 April 2012 (UTC)[reply]

A couple of obscure textbooks (see article), one chemical encyclopedia, and Greenwood & Earnshaw's "Elements" state that IFCL2 and IF2Cl have been obtained. However they do not provide any source, and since the language is almost identical, it is likely that they copied each other on that. I could not find any paper on those compounds through Google or GoogleScholar; they do not seem to be listed in PubChem or other similar databases, nor in the online catalog of any Chinese company 8-). However I do not have access to CAS, and my Google searches may not have been thorough enough. Good luck. --Jorge Stolfi (talk) 13:07, 28 February 2013 (UTC)[reply]

PS. If along the way you find references to lead carbide, I would like to know about that too. 8-) --Jorge Stolfi (talk) 13:07, 28 February 2013 (UTC)[reply]

Need improvement[edit]

Moved anon commentary from article page:

This chart unfortunately does not cover the large range of interhalogens that have been formed over the past two decades. Some more would be ICl2-, ICl4-, ICl2+, I5- to I29- , Br3-, I3Br4- and IBr2- . Ref: Aragoni et al. Reactions of Halogens/Interhalogens with Polypyridyl Substrates: The Case of 2,4,6-Tris(2-pyridyl)-1,3,5-triazine. Eur. J. Inorg. Chem. 2008, 3921–3928

This info should be incorporated into the article somehow.—Tetracube (talk) 23:06, 16 July 2009 (UTC)[reply]

Astatine[edit]

Any info?Naraht (talk) 19:41, 24 June 2010 (UTC)[reply]

Yes – see the article. Double sharp (talk) 12:49, 3 January 2013 (UTC)[reply]

All-halogen salts[edit]

One could conceive of a salt composed of two interhalogen ions, with three or more different halogens involved, but I don't find any evidence for their existence. Lavateraguy (talk) 13:52, 3 April 2012 (UTC)[reply]

As said in the article, BrF
₃ ionizes spontaneously to BrF⁺
₂ BrF⁻
₄ in the liquid state. Is the solid ionic too? --Jorge Stolfi (talk) 13:12, 28 February 2013 (UTC)[reply]

Is IF7 chemically inert?[edit]

Although IF₇ indeed has no lone pair on the central iodine atom, it is fairly reactive and a strong fluorinating agent (according to the Greenwood book). As far as I understand this is not what chemically inert means. Am I missing something here? Szaszicska (talk) 04:07, 13 May 2013 (UTC)[reply]

No, you're not; IF₇ is indeed a strong oxidizing and fluorinating agent. (But now I'm wondering where the article states that it is chemically inert. Has it been removed already?) Double sharp (talk) 06:49, 12 August 2013 (UTC)[reply]

Iodine pentafluoride[edit]

I read the following about iodine pentafluoride: "It reacts with elements, oxides and carbon halides." Imagine that! It reacts with elements! Still giggling. Perhaps someone with a chemistry background could clarify which elements? — Preceding unsigned comment added by 70.195.194.119 (talk) 11:31, 4 June 2014 (UTC)[reply]

Astatine monofluoride[edit]

It seems from the article that Astatine monofluoride (AtF) doesn't exist. I'm guessing it has something to do with the high reactivity of fluorine. Can anyone explain this?Anachor (talk) 17:32, 11 November 2014 (UTC)[reply]

From astatine: "No astatine fluorides have been discovered yet. Their absence has been speculatively attributed to the extreme reactivity of such compounds, including the reaction of an initially formed fluoride with the walls of the glass container to form a non-volatile product. Thus, although the synthesis of an astatine fluoride is thought to be possible, it may require a liquid halogen fluoride solvent, as has already been used for the characterization of radon fluorides." I'll add it to this article. Double sharp (talk) 12:42, 8 February 2015 (UTC)[reply]

P.S. Note that astatine fluorides would probably be ionic, given the cationic chemistry of At and Rn (RnF₂ is also ionic). Double sharp (talk) 14:21, 20 March 2018 (UTC)[reply]

First sentence[edit]

The first sentence is not correct. It reads, "a molecule whose atom contains two or more different halogen atoms". How can an atom contain two or more atoms?2601:640:4000:8CD0:34CD:4D03:7568:8F68 (talk) 00:21, 18 December 2015 (UTC)[reply]

I edited the definition. It ought to be okay now. Double sharp (talk) 07:58, 18 December 2015 (UTC)[reply]

Iodine trichloride is heavier than AtI.[edit]

3*2(35.45)+2(126.90)=212.70+253.80=466.50 g/mol>210+126.90=336.90 g/mol. Alfa-ketosav (talk) 07:48, 26 August 2018 (UTC)[reply]

Corrected. Thank you! Double sharp (talk) 15:23, 26 August 2018 (UTC)[reply]

Ternary interhalogen[edit]

In Polyhalogen ions#Polyhalogen cations, the table claim that IF₇ + BrF₃ → [IF₆]⁺[BrF₄]⁻, which is a ternary interhalogen consist of fluorine, bromine and iodine. Is it correct? Nucleus hydro elemon (talk) 07:36, 17 December 2022 (UTC)[reply]
