New insights into the oxidation of phenoxatellurine with sulfuric acid
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.
期刊介绍：
This journal is committed to the publication of short communications, original research, and review articles within the field of main group metal and semi-metal chemistry, Main Group Metal Chemistry is an open-access, peer-reviewed journal that publishes in ongoing way. Papers addressing the theoretical, spectroscopic, mechanistic and synthetic aspects of inorganic, coordination and organometallic main group metal and semi-metal compounds, including zinc, cadmium and mercury are welcome. The journal also publishes studies relating to environmental aspects of these metals, their toxicology, release pathways and fate. Articles on the applications of main group metal chemistry, including in the fields of polymer chemistry, agriculture, electronics and catalysis, are also accepted.
