Abstract The oxidation of phenoxatellurine (PT) with conc. H2SO4 was reinvestigated. Two crystalline products, namely [PT2][H3O](SO4H)3 (1) and [PT](SO4) (2) were isolated and fully characterized by X-ray crystallography. The structure of 1 features [PT2]2+ dications giving rise to double-decker structures with two parallel PT layers that arise from dimerisation of two radical cations [PT]˙+. The [PT2]2+ dications and the hydrogensulfate ions are associated via secondary Te···O interations. The oxonium ion and the hydrogensulfate ions are involved in hydrogen bonding. The structure of 2 comprises ion pairs consisting of [PT]2+ dications and sulfate ions, which form a 2D coordination polymer. In addition, adjacent sulfate ions in the crystal lattice bind to tellurium atoms via secondary secondary Te···O interations.

用硫酸氧化苯氧紫草碱的新见解

摘要 苯氧蝶呤 (PT) 与浓度的氧化。重新研究了 H2SO4。分离出两种结晶产物，即 [PT2][H3O](SO4H)3 (1) 和 [PT](SO4) (2)，并通过 X 射线晶体学进行充分表征。1 的结构具有 [PT2]2+ dications，产生双层结构，具有两个平行的 PT 层，由两个自由基阳离子 [PT]˙+ 的二聚化产生。[PT2]2+ dication 和硫酸氢根离子通过次级 Te…O 相互作用缔合。氧鎓离子和硫酸氢根离子参与氢键。2 的结构包含由 [PT]2+ dications 和硫酸根离子组成的离子对，它们形成 2D 配位聚合物。此外，晶格中相邻的硫酸根离子通过二次二次 Te···O 相互作用与碲原子结合。
