Web2. Metal hydrides in MHAT reactions 2.1 Formation of metal hydride Metal hydride species have been a longstanding topic of study in organometallic chemistry, and bond dissociation enthalpies (BDE) are known for many M–H bonds in classic 18-electron organometallic hydride complexes. 22 Measured BDE values are generally 52 kcal mol … WebIn chemistry, a hydride is formally the anion of hydrogen (H −). The term is applied loosely. At one extreme, all compounds containing covalently bound H atoms are called hydrides: water (H 2 O) is a hydride of oxygen, ammonia is a hydride of nitrogen, etc.For inorganic chemists, hydrides refer to compounds and ions in which hydrogen is covalently …
