Developments on the chemistry of tellurium and selenium azides

摘要

We have been carrying out systematic studies on the preparation and properties of tellurium. halide and pseudohalide compounds with a focus on tellurium. azides. We were successful in the synthesis of various tellurium azides of both covalent and ionic nature. Several tellurium(IV) azides, tellurium(II) azides, and the first tellurium(VI) azides can be prepared in reasonable amounts. Vie first structural information of selenium azides is obtained for covalent and ionic derivatives, and spectroscopic data for the existence of selenium(IV) polyazides.
