WebMetal hydrides are compounds of one or more metal cations (M+) and one or more hydride anions (H − ). When pressurised, most metals bind strongly with hydrogen, resulting in stable metal hydrides that can be used to store hydrogen conveniently on board vehicles. Examples of metal hydrides are LaNi 5 H 6, MgH 2, and NaAlH 4. Web25 nov. 2024 · The “hydricity” of a species refers to its hydride-donor ability. Similar to how the pK a is useful for determining the extent of dissociation of an acid, the hydricity plays a vital role in understanding hydride-transfer reactions. A large number of transition-metal-catalyzed processes involve the hydride-transfer reaction as a key step.
