Pseudohalogens are inorganic binary compounds of the form XY where X can be cyanide, cyanate, thiocyanate, and Y is one of these same groups or a true halogen. Not all combinations are known or necessarily stable. As an example, there is cyanogen, (CN) 2, and iodine cyanide (ICN). The corresponding anions behave in many circumstances as halogens where the presence of internal double or triple bonds does not seem to affect their chemical behavior. Other groups are also sometimes considered as pseudohalides such as azide anions (N3) which form for example fluorine azide or chlorine azide or even triflate anions (CF3SO3).
