The hottest (?) chemical flame (cyanogen-oxygen).

I just stumbled on an old paper (Conway J.B.; Grosse A.V. The Cyanogen-Oxygen Flame under Pressure. JACS 1958, 80(12), 2972-2976) where cyanogen-oxygen flames were studied. That seems like a pretty suicidal chemistry (cyanogen is extremely toxic). It's interesting that a lot of people studied different aspects of these flames (and mixtures). The paper calls cyanogen-oxygen flame "one of the hottest chemical flames", with its measured temperature being 4367C°. I wonder what is hotter, something like cyanogen-ozone or cyanogen-fluorine flame?

According to Guiness Records I think the hottest is:
C4N2 + O2
flame temperature is 5260K.
it also considered as rocket propellant.

(C4N2 is dicyanoacethylene www.en.wikipedia.org/wiki/Dicyanoacetylene)
