Binary transition metal hydrides
Binary metal hydrides Many transition metals form compounds with hydrogen, called binary hydrides: binary, because these compounds contain only two elements, and hydride, because the hydrogenic ligand is assumed to have hydridic (H -like) character. These compounds are invariably insoluble in all … See more Transition metal hydrides are chemical compounds containing a transition metal bonded to hydrogen. Most transition metals form hydride complexes and some are significant in various catalytic and synthetic reactions. The term … See more Hydride transfer Nucleophilic main group hydrides convert many transition metal halides and cations into the corresponding hydrides: MLnX + LiBHEt3 → HMLn + BEt3 + LiX These conversions are metathesis reactions, and the … See more The determination of structures of metal hydrides can be challenging since hydride ligands do not scatter X-ray well, especially in comparison to the attached metal. … See more An ill-defined copper hydride had been described in the 1844 as resulting from treatment of copper salts with hypophosphorous acid. It was subsequently found that hydrogen gas was absorbed by mixtures of transition metal salts and See more The values shift by <6 kJ/mol upon substitution of CO by a phosphine ligand. The M-H bond can in principle cleave to produce a proton, hydrogen radical, or hydride. See more The rates of proton-transfer to and between metal complexes are often slow. Many hydrides are inaccessible to study through See more Late transition metal hydrides characteristically show up-field shifts in their proton NMR spectra. It is common for the M-H signal to appear between δ-5 and -25 with many … See more WebMetal hydrides are of considerable importance in chemical synthesis as intermediates in catalytic hydrogenation reactions. Transition metal atoms react with dihydrogen to …

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.
