通过硼烷阴离子网-B_3H_8~-和闭-B_(10)H_(10)~(2-1)与一系列卤化铵反应合成出十五种新的硼烷阴离子铵盐。这些新化合物均经元素分析和红外光谱鉴定。它们的差热分析结果表明:B_(10)H_(10)~(2-)铵盐的热稳定性高于B_3H_8~-铵盐;在季铵离子中导入氨基以后,化合物的热稳定性降低,并且导入的氨基愈多,化合物愈不稳定。
Fifteen novel borane anion ammonium salts were synthesized by the reaction of a series of ammonium halides with the borane anion network -B_3H_8 ~ - and-B_ (10) H_ (10) ~ (2-1). These new compounds were identified by elemental analysis and infrared spectroscopy. The results of their differential thermal analysis showed that the thermal stability of B_ (10) H_ (10) ~ (2-) ammonium salts was higher than that of B_3H_8 ~ -ammonium salts. The thermal stability of the compounds decreased after the introduction of amino groups into quaternary ammonium ions , And the more amino groups introduced, the less stable the compound is.
