Abstract

This is a study involving some of the chemistry of osmium tetroxide in perchloric acid solution. The research was originally instigated from a seminar report on the ruthenium III thiocyanate complex ion which was studied in perchloric acid solution. The seminar report given by Craig Townsend discussed how a spectrophotometric study by Yaffe and Voight (1951) was made of the ruthenium III thiocyanate complex ion, Similar possibilities were recognized as being possible in attacking the problem of an osmium thiocyanate complex or complexed. Some of the chemistry involved in the study of the ruthenium III thiocyanate complex will be discussed later. It will now suffice to say that the complex was studied by reacting ruthenium IV perchlorate and sodium thiocyanate to produce the complex ion. Townsend (1953), following the general procedure of Yaffe and Voight, took osmium tetroxide and sodium thiocyanate in a perchloric acid solution and reacted them to produce a rose colored osmium thiocyanate complex ion. He then determined a general formula and a value for the dissociation constant for the complex. Many problems were encountered in the Townsend study; and, therefore, there was reason for further study along these same lines. Some of the general characteristics of osmium and its related elements will be noted first.
