Although many volatile binary boron hydride compounds are known, binary aluminum hydride chemistry is limited to the polymeric (AlH3)n solid. The reaction of laser-ablated aluminum atoms and pure H2 during codeposition at 3.5 kelvin, followed by ultraviolet irradiation and annealing to 6.5 kelvin, allows dimerization of the intermediate AlH3 photolysis product to form Al2H6. The Al2H6molecule is identified by seven new infrared absorptions that are accurately predicted by quantum chemical… Expand
Unexpected Stability of Al4H6: A Borane Analog?
TLDR
A combined anion photoelectron and density functional theory computational study of the Al4H –6 anion and its corresponding neutral, Al4h6, showed that Al4 H6 can be understood in terms of the Wade-Mingos rules for electron counting, suggesting that it may be a borane analog. Expand
Mercury dihydride forms a covalent molecular solid.
TLDR
Atomic mercury in solid hydrogen reacts when subjected to mercury arc irradiation to form the linear HgH2 molecule with strong IR absorptions at 1902 and 1905, characterized by strong IR absorption at 1802, 739 and 673 cm(-1) and by decomposition at 150-170 K. Expand
Photoelectron spectroscopy of boron aluminum hydride cluster anions.
TLDR
Boron aluminum hydride clusters are studied through a synergetic combination of anion photoelectron spectroscopy and density functional theory based calculations to reveal significant geometrical changes upon substitution of aluminum atoms by boron atoms. Expand
Alanate anion, AlH4(-): photoelectron spectrum and computations.
TLDR
The alanate anion, AlH4(-), was generated in the gas phase using a pulsed arc cluster ionization source and its photoelectron spectrum was measured with 193 nm photons, resulting in a broad feature, spanning electron binding energies from 3.8 eV to over 5.3 eV. Expand

TLDR
The postulation is made that binuclear divalent titanium (TiII) and mononuclear silicon (SiII) species might serve as active sites for the H2 attachment reaction for hydridoalanates doped with Ti salts and hydridoborates doping with SiO2, respectively. Expand
Matrix Infrared Spectra and Quantum Chemical Calculations of Ti, Zr, and Hf Dihydride Phosphinidene and Arsinidene Molecules.
TLDR
Comparison of calculated agostic and terminal bond lengths and covalent bond radii for HP═TiH2 with computed bond lengths for Al2H6 finds that these strong agostic Ti-H bonds are 18% longer than single covalENT bonds, and the bridged bonds in dialane are 10% shorter than the terminal Al-H single bonds, which show that these agostic bonds can also be considered as bridged Bonds.
