A highly explosive gold compound. Several chemical species have been considered, but all are thought to have Au-N bonds. The first was obtained in 1886 by reacting gold(I) oxide with ammonia, and was thought to have the composition Au 3 N・NH 3. The gray powder obtained by reacting chloroauric acid HAuCl 4 with aqueous ammonia was thought to be a mixture of Au 2 O 3 ・3NH 3 and HNAuCl・NH 3. Other examples include Au(OH) 3 ・3NH 3 and Au 2 O 3 ・2NH 3 , but neither the composition nor the structure is clear. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
きわめて爆発性の高い金の化合物。いくつかの化学種が考えられているが,いずれもAu-N結合をもつと思われる。1886年に酸化金(I)とアンモニアとの反応で得られたものが最初で,Au3N・NH3の組成と考えられた。また塩化金酸HAuCl4とアンモニア水との反応で得られた灰色粉末はAu2O3・3NH3とHNAuCl・NH3の混合物と考えられた。その他Au(OH)3・3NH3,Au2O3・2NH3などがあるが,組成,構造ともに明確ではない。
