BH
BH is a metastable, metallic boron hydride compound investigated for its utility in hydrogen storage applications.
About BH
BH is a metastable boron-based hydride that exhibits metallic electronic characteristics. As a member of the hydrogen storage hydride class, it is a subject of significant interest in materials science due to its unique structural chemistry and potential for high-density hydrogen containment.
With extensive data available across multiple structural databases, this compound serves as a critical reference point for understanding the bonding behavior of light-element hydrides. Its metallic nature distinguishes it from many insulating hydride counterparts, making it a focal point for research into unconventional storage media.
Key Properties
Cross-validated computational properties for BH, aggregated across 4 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.

How It Compares
Within the hydrogen storage hydrides class.
Unlike the highly stable ionic hydrides such as LiH or CaH2, BH exists in a metastable state, which presents distinct challenges and opportunities for synthesis and kinetic control. While it shares the fundamental goal of hydrogen storage with compounds like AlH3 and MgH2, its metallic electronic character sets it apart from these more traditional, typically non-metallic hydride systems.
