short notes on interhalogen compounds

An interhalogen compound is a molecule which contains two or more different
halogen atoms (fluorine , chlorine, bromine,
iodine , or astatine) and no atoms of elements from any other group.
Most interhalogen compounds known are binary (composed of only two distinct elements). Their formulae are generally XY n , where n = 1, 3, 5 or 7, and X is the less
electronegative of the two halogens. They are all prone to hydrolysis , and ionise to give rise to polyhalogen ions.
No interhalogen compounds containing three or more different halogens are definitely known, [1] although a few books claim that
IFCl 2 and IF2 Cl have been obtained, [2][3][4]
[5] and theoretical studies seem to indicate that some compounds in the series BrClF n are barely stable. [6]
