Nitrosyl Bromide, NOBr
The direct union of nitric oxide with bromine occurs when the gas is led into bromine till no further absorption takes place at temperatures between -7° and -15° C. If the temperature is above -7° C., the additive compound NOBr.Br2 is formed.
Sodium bromide and nitrosyl sulphuric acid react to form nitrosyl bromide:

Properties
Nitrosyl bromide is a brownish-black liquid, boiling at -2° C. with dissociation. Generally speaking, nitrosyl bromide shows very similar properties to nitrosyl chloride.
The heat of formation of nitrosyl bromide is between 9.000 and 10.500 Cals.
The fusion curve of bromine and nitric oxide shows a eutectic at - 40° C. corresponding to NOBr3 or NOBr.Br3, and another at -55° C. which corresponds to NOBr2 and NOBr.
The compound NOBr3 is a brownish opaque liquid which boils at 32° C. with decomposition. The density at 20° C. is 2.637.
The heat of formation at 22° C. is 27.000 Cals.
Many organic compounds react with nitryl fluoride.
