B2H5
B2H5 is a boron-hydrogen compound classified as a wide-gap insulating hydride with potential applications in solid-state hydrogen storage.

About B2H5
B2H5 is a boron-based hydride that functions as a wide-gap insulator. Its electronic structure and proximity to the thermodynamic hull suggest it is a viable candidate for synthesis and investigation within the broader family of hydrogen storage materials. As a member of the borane-related hydride class, it is studied for its ability to store hydrogen in a compact, solid-state form. Its stability profile makes it a subject of interest for researchers aiming to develop efficient, high-density energy carriers.
Key Properties
Cross-validated computational properties for B2H5, aggregated across 2 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.
Within the class of hydrogen storage hydrides, B2H5 occupies a distinct position compared to more conventional ionic hydrides like LiH or CaH2. While those materials are typically characterized by their simple lattice structures, B2H5 exhibits the complex bonding behavior common to boron-hydrogen systems, placing it closer in character to BH3 than to the stable, binary metal hydrides.
