exhaustive list of inorganic gases

soreff - 28-12-2014 at 11:54

Has anyone listed the full set of inorganic gases at standard
temperature (25C) and pressure (1 atm)?
The closest I've seen is air liquid's "gas encyclopedia":

It covers H2, the noble gases, the gaseous halogens and interhalogens,
the first row gases N2 and O2, the hydrides that I know of, B2H5, SiH4,
GeH4, the sulfur and nitrogen oxides, and even WF6, but it seems to miss ClO3F.

Is there a complete list somewhere?
Many Thanks!

Best wishes,

Not seeing Cl2O, ClO2,...Br2O,...per your link.

Also, there is the question as to whether your list criteria covers intermediate gas compounds (for example, the ClO dimer which is significant in atmospheric chemistry).

Here are some more gases, including organic ones:

Only in german but still useful if you need some basic information about many gases.

I remember I wanted to use the OP link as a ref for wiki when I wrote the data for an article, but when I compared the physical data of a few gasses from that site to Wikipedia and other, I found they don't quite match, there were small differences. Not sure which is more accurate.

Many Thanks! The
list does look substantially more complete. I also see SeF6 and TeF6 on that list, but not in the original link.

Re ClO - good point! I guess I'd count the ClO/Cl2O2 pair as one
equilibrium mix, like the classic NO2/N2O4 equilibrium.
Of course, then there is the question of which equilibria are fast enough
that one should just count the equilibrium mixture, and which are slow
enough to count the individual substances as separate...
Perhaps somewhere between one second and one day as a plausible
dividing line for a "bottleable" material?

I know 182 inorganic gases.
