Preparation and structure of Te4N2Cl8(AsF6)2·2SO2 containing Te4N2Cl82+, the first tellurium–nitrogen–halogen cation

Abstract

The reaction Of TeCl₄ and N(SiMe₃)₃, followed by the addition of AsF₅ gives Te₄N₂Cl₈(AsF₆)2·2SO₂, shown by its X-ray crystal structure to contain Te₄N₂Cl₈²⁺([(Cl₃Te)[graphic omitted]Te(Cl)]²⁺), the first tellurium–nitrogen–halogen cation.
