The 1:1 and 1:2 adducts of Aluminum borohydride (cas 16962-07-5) (Al(BH4)3) and the Lewis base triethylenediamine (TEDA) and their thermal decomposition products were synthesized and structurally characterized by Raman spectroscopy, X-ray diffraction, and thermogravimetric analysis. Both adducts are more stable than Al(BH4)3 with respect to thermal decomposition and release of diborane. The structural analysis indicates that stabilization occurs through the donation of electron density through the N–Al dipolar bonds, leading to a more ionic character of the borohydride subunit. The 1:2 adduct, which has more electron donation, shows more ionic character and greater stability. For both adducts, the displaced borohydride group forms a dipolar bond with the second N lone pair of the TEDA, preserving much of the H content of the material. Decomposition occurs by internal rearrangement of borohydride, forming 1:1 and 1:2 TEDA·BH3 adducts, followed by release of H2 from the Al bonding center. The relative stability of the adducts encourages continuing exploration of Lewis base-stabilized borohydrides as an improved hydrogen storage material.
