Catalyzed Complex Metal Hydrides
MRS Bulletin, 2002AbstractComplex hydrides are mixed ionic–covalent compounds that can serve as reversible H2storage media only when they are catalyzed by a transition metal such as Ti. As the prime example, the phenomenology of Ti-catalyzed sodium alanate (NaAlH4) is reviewed from a historical perspective.

Trinuclear rhodium hydride complexes
Dalton Transactions, 2011Three novel trinuclear rhodium hydride complexes of the type {[Rh(PP*)H](3)(μ(2)-H)(3)(μ(3)-H)}[BF(4)](2) containing diphosphines Tangphos, t-Bu-BisP* and Me-DuPHOS have been synthesised. The new compounds are very stable. Their structures have been characterized by X-ray analysis in the solid state and by NMR-spectroscopic investigations in solution.

NaAlH4 is amongst the most advanced and intensely investigated hydrogen storage materials today. It reaches a storage capacity of more than 5 wt.% at around 100 °C. By suitable doping with catalysts, the re- and de-hydrogenation kinetics can be dramatically improved so that re-hydrogenation times on the order of minutes can be achieved.

AbstractReaction of the ethylene hydride complex trans‐[(dmpe)2MnH(C2H4)] (1) with Et2SiH2 at 20 °C afforded the silylene hydride [(dmpe)2MnH(=SiEt2)] (2 a) as the trans‐isomer. By contrast, reaction of 1 with Ph2SiH2 at 60 °C afforded [(dmpe)2MnH(=SiPh2)] (2 b) as a mixture of the cis (major) and trans (minor) isomers, featuring a Mn‐H‐Si interaction ...

Journal of the Chemical Society A: Inorganic, Physical, Theoretical, 1967
The stable colourless crystalline complex, (Et3P)2Pd(H)Cl is obtained by the reduction of (Et3P)2PdCl2 with trimethylgermane at 40°. Reduction of (Et3P)2PdBr2 is slow unless palladium black is added. The analogous reaction with (Et3P)2NiBr2 gives a highly unstable nickel hydride complex.

The hydride route to the preparation of dinitrogen complexes
Chemical Communications, 2010That the inert dinitrogen molecule can act as a ligand to a transition metal complex is one of the key discoveries in inorganic chemistry of the past century. This feature article summarises a body of work up to 2010 that describes a particularly attractive route to dinitrogen complexes that involves the direct reaction of N(2) with metal hydride ...

FOLLOWING a recent investigation of the structure of some rhodium(III) and iridiuni(III) tertiary arsine complexes1, which were shown to contain a metal-hydrogen bond, we have examined certain tertiary phosphine compounds of platinum and suggest that these also are complex metal hydrides.

Hydridic character of early transition metal hydride complexes
Journal of Organometallic Chemistry, 1978Abstract The cendency of transition metal hydride complexes to behave as true hydrides, as measured by ability to reduce ketones, appears to depend strongly on the position of the metal in the Periodic Table; the strongest such behavior is exhibited by complexes of metals furthest to the left in the transition series.

Effects of microwave irradiation on metal hydrides and complex hydrides
Journal of Alloys and Compounds, 2007Abstract Effects of single-mode microwave irradiation on metal hydrides, MH n (LiH, MgH 2 , CaH 2 , TiH 2 , VH 0.81 , ZrH 2 , and LaH 2.48 ) and complex hydrides MBH 4 (LiBH 4 , NaBH 4 , and KBH 4 ) were systematically investigated. Among the metal hydrides, TiH 2 , VH 0.81 , ZrH 2 , and LaH 2.48 exhibit a rapid heating by microwave irradiation,

Mechanochemical synthesis of complex hydrides
Russian Journal of Inorganic Chemistry, 2012This survey concerns the effects of mechanical treatment on the properties of simple and complex hydrides and solid-phase reactions that occur during mechanical activation of hydride systems. Special attention is paid to the mechanochemical synthesis of hydroborates and hydroaluminates.
