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… 
Unexpected Stability of Al4H6: A Borane Analog?
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.
Photoelectron spectroscopy of boron aluminum hydride cluster anions.
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.
Alanate anion, AlH4(-): photoelectron spectrum and computations.

Matrix Infrared Spectra and Quantum Chemical Calculations of Ti, Zr, and Hf Dihydride Phosphinidene and Arsinidene Molecules.
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.
