BaO6
BaO6 is a metastable, semimetallic compound of barium and oxygen that exhibits complex structural behavior.
About BaO6
BaO6 is a complex inorganic compound composed of barium and oxygen. It is characterized by a near-zero-gap electronic structure, placing it in the semimetallic regime, which distinguishes it from typical insulating barium oxides. Its metastable nature suggests a unique structural landscape, supported by multiple reported configurations across various databases.
Because it exists in a metastable state, this compound represents a fascinating subject for high-pressure research and materials synthesis. Its electronic properties make it a candidate for studies involving unconventional bonding and electronic transitions, providing insight into how oxygen-rich environments influence the behavior of heavy alkaline earth metals.
Key Properties
