Gaseous compounds of metals

I know Stannane (SnH4) is a gas at STP. Are there gaseous compounds containing iron, magnesium, silicon, or other metals that are gaseous at room temperature, or close to it?

Or perhaps more importantly, what’s a good reference to use if I wanted to get a list of such compounds?

OK, I suppose Si is not a metal…

nickel carbonyl

Uranium hexafluoride (UF[sub]6[/sub]) is a liquid which boils at a very low temperature – it’s historically famous as being the compound used in the gaseous diffusion method of concentrating U-235 out of native (99%+ U-238) uranium.

Tungsten(VI)_fluoride, the densest known gas.

And if you’re not too picky, germane, hydrogen telluride, selenium hexafluoride, from a quick browse through the CRC Handbook

THE standard reference for science geeks is the CRC Handbook of Chemistry and Physics, now in its umpteenth edition. There’s a section on Inorganic Compounds which lists a huge number of such, and gives their melting points, boiling points, crystal structure, etc. With that you can easily ferret out the metal-containing compounds at room temperature.

Any decent chemical catalog – Alfa or Sigma or whatever will do the same for the ones they carry.

And is that relevant to this discussion? :dubious:

:smiley:

Thanks, I finally found my copy of CRC and got the answer.

Unfortunately it looks like the most volatile compound of Fe is iron pentacarbonyl, whose boiling point is above 100 C. Unless anyone knows of one I missed?
