The reaction of azide with organotellurium(VI) halides Ph₅TeBr and cis-(biphen)₂TeF₂ (biphen= 2,2'-biphenyldiyl) resulted in the formation and isolation of Ph₅TeN₃ (1) and cis-(biphen)₂Te(N₃)₂ (2),which are the first tellurium(VI)-azide species. In addition to spectroscopic data, both crystal structureshave been determined. Furthermore, the stability of possible Te(VI) species with higher azide contentsPh_xTe(N₃)_6-x and Me_xTe(N₃)_6-x as well as the syntheses and properties of their Ph/Me_xTeF_y precursorswas investigated, including the crystal structure determination of trans-Ph₂TeF₄ (3). Ab initio and densityfunctional studies of all molecules regarding the structures and electronic populations were performed.
