As2O10Sc2
As2O10Sc2 is a semiconducting scandium arsenate compound characterized by its metastable nature and structural complexity.
About As2O10Sc2
As2O10Sc2 is a complex inorganic compound composed of scandium, arsenic, and oxygen. As a semiconducting material, it represents a niche area of solid-state chemistry where transition metal oxides interface with pnictogen-based polyanions.
Due to its position above the thermodynamic hull, this compound is considered metastable, which presents unique challenges for synthesis and characterization. It remains a subject of interest for researchers investigating the structural diversity of scandium-based mineral-like frameworks.
Key Properties
