O22Re4V4
O22Re4V4 is a metastable, semiconducting rhenium-vanadium oxide that exists in several distinct structural forms.
About O22Re4V4
O22Re4V4 is a complex oxide composed of rhenium, vanadium, and oxygen. As a semiconducting material, it exhibits electronic properties that distinguish it from simple metallic oxides, making it a subject of interest for fundamental solid-state research.
Despite its existence in multiple structural configurations across databases, the compound is identified as being above the thermodynamic hull. This suggests that it is a metastable phase, requiring specific synthesis conditions to stabilize its unique atomic arrangement.
Key Properties
