Spectrophometric studies of complexes of aromatic hydrocarbons and halogens have been of interest in recent years. Lately, this interest has expanded to other halogen complexes. This paper is a report of the studies performed on some halogen complexes of 2,2'-bipyridine. Three systems were studied spectrophometrically in carbon tetrachloride. These systems were 2,2'-bipyridine, iodine monobromide and iodine monochloride. The following results were obtained in the study. 1. Iodine and 2,2'-bipyridine, in carbon tetrachloride solution, form a complex of 1:1 composition. The formation constant for this complex, using the Ketelaar method, is 5:01. 2. Iodine monobromide and 2,2'-bipyridine, in carbon tetrachloride solution, form a complex of 1:1 composition. The formation constant for this complex, using the Ketalaar method, in 10.7. 3. Iodine monochloride and 2,2'-bipyridine, in carbon tetrachloride solution, form a complex of undetermined composition. The method of continuous variation indicated a composition of 1:1 for the complex, but the determination of the formation constant was not possible.
