文摘

A metathesis reaction between unsolvated NaB₃H₈ and NH₄Cl provides a simple and high-yield synthesis of NH₄B₃H₈. Structure determination through X-ray single crystal diffraction analysis reveals weak N鈭扝^未+---H^{未鈭?/sup>鈭払 interaction in NH₄B₃H₈ and strong N鈭扝未+---H未鈭?/sup>鈭払 interaction in NH₄B₃H₈路18-crown-6路THF adduct. Pyrolysis of NH₄B₃H₈ leads to the formation of hydrogen gas with appreciable amounts of other volatile boranes below 160 掳C. Hydrolysis experiments show that upon addition of catalysts, NH₄B₃H₈ releases up to 7.5 materials wt % hydrogen.}
