Borane · borine, trihydridoboron
Borane is a reactive, hydrogen-rich covalent hydride that serves as a key precursor in the development of advanced chemical storage and synthesis materials.
About Borane
Borane is a fundamental boron-hydrogen compound characterized by its insulating electronic nature. As a member of the hydrogen storage hydride family, it represents a lightweight building block for complex borohydride materials, offering a high theoretical capacity for hydrogen density.
Its position near the thermodynamic hull suggests that while it is highly reactive, it remains a critical subject for synthetic research. The compound is extensively studied for its role as a precursor in chemical synthesis and as a foundational model for understanding hydrogen-rich storage systems.
Key Properties
Cross-validated computational properties for Borane, 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.

How It Compares
Within the hydrogen storage hydrides class.
Unlike the more robust and ionic alkaline earth hydrides such as MgH2 or CaH2, Borane exhibits distinct covalent character and higher reactivity. While stable ionic hydrides like LiH are frequently utilized for their straightforward hydrogen release, BH3 serves as a more complex, high-energy-density component often found in the structural framework of more stable borohydride salts like NaBH4.
