Tl2S2O3
Tl2S2O3 is a metastable, semiconducting inorganic compound composed of thallium, sulfur, and oxygen.

About Tl2S2O3
Tl2S2O3 is a complex thallium-based compound characterized by its semiconducting electronic nature. It represents a niche area of inorganic chemistry where the interplay between heavy metal cations and sulfur-oxygen polyanions creates unique structural configurations.
Despite its existence in multiple reported structures, the compound is categorized as being above the thermodynamic hull. This indicates that it is a metastable phase, which is of significant interest to researchers studying phase stability and the synthesis of complex chalcogenide materials.
Key Properties
