dc.description.abstractFor the first time, in situ monitoring of uninterrupted mechanochemical synthesis of two bimetallic amidoboranes, M2Mg(NH2BH3)(4) (M=Li, Na), by means of Raman spectroscopy, has been applied. This approach allowed real-time observation of key intermediate phases, and a straightforward follow-up of the reaction course. Detailed analysis of time-dependent spectra revealed a two-step mechanism through MNH2BH3 center dot NH3BH3 adducts as key intermediate phases which further reacted with MgH2, giving M2Mg(NH2BH3)(4) as final products. The intermediates partially take a competitive pathway toward the oligomeric M(BH3NH2BH2NH2BH3) phases. The crystal structure of the novel bimetallic amidoborane Li2Mg(NH2BH3)(4) was solved from high-resolution powder diffraction data and showed an analogous metal coordination to Na2Mg(NH2BH3)(4), but a significantly different crystal packing. Li2Mg(NH2BH3)(4) thermally dehydrogenates releasing highly pure H-2 in the amount of 7 wt.%, and at a lower temperature then its sodium analogue, making it significantly more viable for practical applications.en
