AbstractThe monoammoniate of calcium amidoborane, Ca(NH2BH3)(2)center dot NH3, was synthesized by ball milling an equimolar mixture of CaNH and AB. Its crystal structure has been determined and was found to contain a dihydrogen-bonded network. Thermal decomposition under an open-system begins with the evolution of about 1 equivalent/formula unit (equiv.) of NH3 at temperatures <100 degrees C followed by the decomposition of Ca(NH2BH3)(2) to release hydrogen. In a closed-system thermal decomposition process, hydrogen is liberated in two stages, at about 70 and 180 degrees C, with the first stage corresponding to an exothermic process. It has been found that the presence of the coordinated NH3 has induced the dehydrogenation to occur at low temperature. At the end of the dehydrogenation, about 6 equiv. (similar to 10.2 wt %) of hydrogen can be released, giving rise to the formation of CaB2N3H.
