ZnH6
ZnH6 is an insulating, hydrogen-rich zinc compound that serves as a theoretical model for studying unstable metal hydride structures.
About ZnH6
ZnH6 is a hydrogen-rich zinc hydride compound characterized by its insulating electronic nature. As a wide-band-gap material, it represents an intriguing case study in high-pressure chemistry and metal-hydrogen bonding interactions. Its structural complexity is highlighted by the multiple configurations identified across various computational databases. Because it resides above the thermodynamic hull, this phase is generally considered unstable under ambient conditions, serving primarily as a theoretical model for understanding the limits of hydride formation. Research into such materials is vital for advancing our fundamental knowledge of chemical bonding in extreme environments.
Key Properties
Cross-validated computational properties for ZnH6, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
