Binary structures antimony

The binary chalcogenides of antimony and bismuth are highly colored compounds that are readily prepared by direct reaction of the elements at 500-900 C. They have rather complex ribbon or layer structures and exhibit semiconductor properties. 

Binary oxides of phosphorus, arsenic and antimony are polycyclic compounds, e.g. E4O6 (E = P, As, Sb), with an adamantane-like structure. Monocyclic... 

The thermolysis is strongly affected by structural features e.g. Westin and Nygren investigated the thermolysis of antimony-containing binary alkoxides with transition metals. The compounds approximate the composition MSb(OEt)5, M = Mn, Fe, Co and Ni. These materials are suitable for sol-gel processes. The gels were heated in the temperature range 50-950 °C and quenched at various temperatures to be examined spectroscopically (I.R. and X-ray powder diffraction). The thermolysis was carried out in both N2 and air. The final products are shown in the equations below ... 

Use the group structure of the periodic table to predict the empirical formulas for the binary compounds that hydrogen forms with the elements antimony, bromine, tin, and selenium. 

This applies to systems involving zinc or cadmium, on the one hand, and nitrogen or bismuth, on the other. For the remaining elements (Zn, Cd-P, As), the formation of solid solutions is most probable, owing to the strong interaction in the primary binary systems. The formation of variable phases based on antimony is predicted, but, because of the metastability of the binary compounds of the primary systems and also the absence of a structural analogy, the problem is complicated and requires a more detailed analysis.
