Hexathionates

Hexathionates are a class of inorganic polythionates with the general formula [S6O6]2-. They are characterized by a chain of six sulfur atoms and six oxygen atoms. The most well-known member of this group is the hexathionate anion itself. These compounds are typically formed through redox reactions involving sulfur and oxidizing agents, or as intermediates in the decomposition of other sulfur-containing species. Their chemical behavior is influenced by the presence of the extended sulfur chain. Hexathionates are generally unstable and can decompose, especially in aqueous solutions, to form simpler sulfur oxyanions. The study of hexathionates has been of interest in inorganic chemistry, particularly in understanding the bonding and reactivity of sulfur chains. Their existence is often detected through spectroscopic methods or by analyzing their decomposition products. While not as common as simpler thionates or dithionates, hexathionates represent a fascinating aspect of sulfur chemistry.
