Unipositive Halogen Complexes

Dodd and R. L. Robi.nson Experimental Inorganic Chemistry.  

A common method for the preparation of these compounds involves the reaction of a silver salt with the halogen in a dry, mildly polar solvent such as chloroform, in the presence of the coordinating base, e.g., pyridine or quinoline. The silver salt may be used in the form of its complex with 

Evidence indicates that the adduct of iod ne(I) chloride and pyridine (synthesis 47) contains unipositive iodine stabilized by coordination with pyridine.

The chloroform filtrate is separated and transferred to a 1-1. flask, and 500 ml. of dry, low-boiling petroleum ether is added. The pale yellow crystalline precipitate is separated by filtration in a moisture-free atmosphere (Fig. 21) and
