UBrO5
UBrO5 is a semimetallic uranium-bromine-oxide compound characterized by its metastable nature and unique electronic properties.
About UBrO5
UBrO5 is a complex inorganic compound containing uranium, bromine, and oxygen. Its electronic character is defined as near-zero-gap, placing it in the semimetallic regime, which is a rare and intriguing property for this specific elemental combination.
Due to its position above the thermodynamic hull, UBrO5 is considered a metastable or unstable phase. Its existence in multiple reported structures suggests that while it may be difficult to synthesize or maintain, it remains a subject of interest for fundamental research into uranium-based chemical systems.
Key Properties
