Two types of structures were seen a needle type bundled structure pointing inward towards the center of the sphere and surface bumps. The needle type structures overall were less than 10 pm in length and less than 1 pm in thickness. To confirm that these structures corresponded to sodium alanate. elemental mapping of the alanate s sodium and aluminum constitutes was made. As can be seen in Fig.5, the presence of intense sodium distribution was noted on the needle structures while the both the surface bumps and needle structures showed the presence of aluminum distribution. These results confirmed spheres filling with the alanate. While these needle structures are not usual for sodium alanate. it is speculated that the porous silica could have provided a nucleation surface for these unique structures formation. Nevertheless, since the samples were exposed to ambient air prior to the... 

Dimethylamine condensed into an evacuated flask containing a soln. of trimethylamine alane in ether, the mixture allowed to warm slowly to room temp., H2 removed when its evolution has ceased, unchanged dimethylamine recondensed into the flask, and the product isolated after no further Hg-evolution is observed bis(dimethylamino)alane. Y 91%.—The use of trimethylamine alane in place of aluminum hydride permits a wider choice of solvent and reaction temp. F. e. and methods s. J. K. Ruff, Am. Soc. 83, 2835 (1961).
