A method of making neopentasilane, the method comprising: contacting perchloroneopentasilane with a reductive effective amount of an alkali metal aluminum hydride in an alkylaluminum compound of formula R.sub.xAlCl.sub.3-x, where R is alkyl having from at least 5 carbon atoms, x is an integer from 1 to 3, and the alkylaluminum compound has a boiling point of at least 250° C., at conditions sufficient to reduce the perchloroneopentasilane, to form a reaction product mixture comprising neopentasilane, and separating the neopentasilane from the product mixture to form a neopentasilane isolate.

A nanoparticle of a decomposition product of a transition metal aluminum hydride compound, a transition metal borohydride compound, or a transition metal gallium hydride compound. A process of: reacting a transition metal salt with an aluminum hydride compound, a borohydride compound, or a gallium hydride compound to produce one or more of the nanoparticles. The reaction occurs in solution while being sonicated at a temperature at which the metal hydride compound decomposes. A process of: reacting a nanoparticle with a compound containing at least two hydroxyl groups to form a coating having multi-dentate metal-alkoxides.
