The DMP-stabilized compounds 1 -3 (figure )) exhibit Tvol. ranging from 56.8 °C for 3 to 87.5 °C for the chloride derivate 2, with the dimeric alane 1 in-between those temperatures with a Tvol. of 74.1 °C. The rest masses (r.m.) are found to be within a range of 1.9 wt.% for 2 to 13.1 wt.% for 1, indicating a higher thermal stability for 2, than for the dihydride 1 and methylhydride 3. As an overall trend, the DMP-stabilized alanes prove to be less volatile in direct comparison to the amine stabilized alanes 4 -6, which is expected considering the higher molecular mass.
