This article should be called Nickel tetracarbonyl but as a google search reveals omitting the tetra is by far more prevalent, I'll leave it for now. Meandmyself 11:11, 24 April 2006 (UTC)
- Google notwithstanding, chemists in US rarely use the prefix tetra. There's only one, in effect. In any case, nomenclature issues are a sink for much wasted energy because such debates engage folks who want to say something but dont know enough chemistry to actually insert useful content. So I learned to avoid debating such issues.--Smokefoot 13:44, 24 April 2006 (UTC)
"liquid death" reference?
What is the reference for the nickname "liquid death?" I have worked with and around Ni(CO)4 for a long time and NEVER heard this phrase. I recommend striking it. Also, lots of chemicals are worse than NiCO)4.--Smokefoot 01:08, 3 May 2006 (UTC)
- The reference is probably me. I certainly know this nickname. I agree that many substances are worse than nickel carbonyl, what is unusual about [Ni(CO)4] are its volatility and its ease of decomposition—greater than iron pentacarbonyl or dicobalt octacarbonyl for example. It is notable as an unexpectedly dangerous compound, in the same vein as nitrogen dioxide. I ask for more input before removing the reference. Physchim62 (talk) 12:33, 3 May 2006 (UTC)
I am cool with leaving the monicker, I hadnt heard the label - but the reputation of this stuff is deservedly bad. Reacts nicely though with PR3.--Smokefoot 13:50, 3 May 2006 (UTC)
- I'm sure it does! It loses carbonyl ligands quite readily, and if you don't give it another π-donor straight away it will deposit sub-micron particles of metallic nickel in parts of your body where you really don't want them. Neither of these two facets of its chemistry is particularly good for human health (there is debate, which is sometimes honest and justified, as to which is the worse...). Maybe we should have a try at writing an article on nickel(0) coordination chemistry? Not easy, but worth a try in my opinion Physchim62 (talk) 15:49, 3 May 2006 (UTC)
First metal carbonyl?
My sense is that Ni(CO)4 is the undisputed first binary metal carbonyl complex. Someone should dig into the broader claim of it being "the first metal carbonyl complex to be made" because CO-Pt or CO-CuCl things might have been known before Mond's work.--Smokefoot 22:14, 24 July 2006 (UTC)
Accidental discovery?
Can somebody back me up that this thing was discovered when Mond's inorganikers tried to pump CO gas through a valve which was made of nickel and found that it kept dissolving?

Nickel carbonyl decomposition
I work with gasoil using a nickel base catalyst in a hydrotreater. Whenever we prepare for cataylst change out we're always aware of the formation of Nickel carbonyl. Can anyone tell me at what temperature does the Ni(CO)4 decompose? The reactor normally runs at 365 deg c, at 13,200kpa. When preparing for catalyst change out we bring the reactor internal temps down to 25-30 deg c prior to dumping catylst.
- In the Mond process it decomposes at 230 deg C according to http://wwwchem.uwimona.edu.jm/courses/nickel.html
- This link says it decomposes at 180 deg C http://science.jrank.org/pages/17186/Mond-process.html

Decomposition in air
Added to hazards section some good news: the vapors don't last long in air. Once your spill finishes evaporating (remember it evaporates quickly, BP=43degC), you only have to wait a minute or two before it's safe again. The carbonyls get displaced by oxygen. This limits its utility as a poison gas.SingingZombie (talk) 01:22, 13 December 2009 (UTC)
Color
It's not actually colorless; it's very pale yellow. See, for instance, http://dictionary.infoplease.com/nickel-carbonyl SingingZombie (talk) 06:51, 14 December 2009 (UTC)
SMILES
I think the SMILES specification would be Ni(C#[O])(C#[O])(C#[O])(C#[O]) for the structure pictured, and Ni([C]=O)([C]=O)([C]=O)([C]=O) for the alternative structure with double bonds. Objections to adding that?

Cigarettes
At university in lecture i learnt it is found in cigarette smoke and causes lung cancer... I know the health risks are included, but sources maybe need including more [or introducing as may be the case]. 128.243.253.102 (talk) 22:56, 20 May 2010 (UTC)
