资源简介：
The monoammoniate of calcium amidoborane, Ca(NH2BH3)2·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 °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 °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.
(∼ 10.2 wt %) of hydrogen can be released, giving rise to the
formation of CaB2N3H.
