The first fully structurally characterized ternary europium palladium hydrides (deuterides) are reported. The most Eu rich compound is Eu(2)PdD(4). Its beta-K(2)SO(4) type structure (space group Pnma, a = 749.47(1) pm, b = 543.34(1) pm, c = 947.91(1) pm, Z = 4) contains tetrahedral 18-electron [PdD(4)](4)(-) complex anions and divalent Eu cations.

AbstractSolid magnesium hydride [MgH2]∞ has been pursued as a potential hydrogen‐storage material. Organic chemists were rather interested in soluble magnesium hydride reagents from mid‐20th century. It was only in the last two decades that molecular magnesium hydride chemistry received a major boost from organometallic chemists with a series of ...

The crystal structure of Ba(3)(AlO(4))H is isotypic with Ba(3)SiS(5) and contains AlO(4)(5-) and H(-) anions. The hydride and oxide anions are coordinated by six Ba and five Ba/one Al atoms in an octahedral geometry. The hydrogen content was examined by MAS-NMR experiments of the deuterated compound.

Nickel hydride complexes, defined herein as any molecules bearing a nickel hydrogen bond, are crucial intermediates in numerous nickel-catalyzed reactions. Some of them are also synthetic models of nickel-containing enzymes such as [NiFe]-hydrogenase. The overall objective of this review is to provide a comprehensive overview of this specific type of ...

BS>Solid-liquid equilibrium was investigated by the method of thermal analysis. The system LiH- Li2O was studied from 0 to 14 mole% Li2O and the system LiH- CaH2 from 0 to 37 mole % CaH2. The other two systems were investigated only at 8.0 plus or minus 0.3 mole% titanium hydride and zirconium hydride in LiH.

We have computed the structure and stability of the xenon hydrides HXeY (with Y = F, Cl, Br, I, CCH, CN, NC) using relativistic density functional theory (DFT) at ZORA-BP86/TZ2P level. All model systems HXeY studied here are bound equilibrium structures, but they are also significantly destabilized with respect to Xe and HY.

Formation of positronium hydride
Physical Review Letters, 1992We report the formation of positronium hydride (PsH), in collisions between positrons and methane. A preliminary value of 1.1\ifmmode\pm\else\textpm\fi{}0.2 eV for the binding energy of PsH is obtained.
