In the German Wikipedia the following claim about fire extinguishing agents is made:

Iodkohlenwasserstoffe haben zwar eine hervorragende Löschwirkung, erlangten wegen ihres exorbitant hohen Preises (in den 1950ern etwa Faktor 10 gegenüber Bromkohlenwasserstoffen) jedoch niemals Bedeutung.

Translated:

Though iodine hydrocarbons have excellent fire extinguishing properties they never became important because of their exorbitant prices (during the 1950s they were approximately 10 times more expensive than bromide hydrocarbons).

Now I am curious because I never heard of iodine hydrocarbons. What are their properties and what advantages would they have over the traditional halogen (fluoride, chloride, bromide) components if price is irrelevant?

  • Funny, Professor Knochel stated in a lecture that if $\ce{Ar-Cl}$ costs $1 per gram, $\ce{Ar-Br}$ will cost $10 per gram and $\ce{Ar-I}$ $1000 per gram resulting in a factor of $100$. – Jan Feb 12 '17 at 18:56
