Antimony general remarks

Determination of antimony using the hydride AAS technique General remarks... 

Other oxyhalides, mostly oxychlorides and oxybromides, result from the controlled hydrolysis of the trihalides, and are of interest for two main reasons. First, they are quite unrelated to the oxyhalides of bismuth. Although both antimony and bismuth form compounds MOX the structures of the antimony compounds are quite different from those of the compounds BiOX, which have been described on p. 408. The more complex oxyhalides of Sb have no analogues among Bi compounds. Second, a feature of the published structures of the antimony oxyhalides is the coordination of Sb by either three or four O atoms. It should perhaps be remarked here that the investigation of the structures of these complex compounds is difficult, and the precise positions of the O atoms are by no means certain. However, it appears that a feature of these compounds is the formation of extended Sb—O systems, generally layers, interleaved with halogen... 

As can be seen from Tables 9.2 and 9.3, for many reactants the composition of the primary gaseous products (oxygen and nitrogen) differs from the equilibrium composition. These products are released, completely or partially, in the form of free atoms. This phenomenon is of remarkable theoretical and practical interest. Some general features of this phenomenon, related to the decompositions of oxides, nitrides and, to some extent, of phosphorus, arsenic, and antimony, are described below.
