除了其他几种应用外，金属叠氮化物还可用于合成氮磷酸盐和二元氮化物。本文提出了一种合成叠氮化物的新方法：以液氨为溶剂，主族金属、过渡金属、稀土金属等与叠氮化银反应，得到相应的金属叠氮化物。本文首次采用低温合成法合成了Mn（N3）2、Sn（N3）2和Eu（N3）2及其氨配合物。也可以更简单地获得Zn（N3）2。在室温和相应的NH3蒸气压下，可以生长双核叠氮化钬[Ho 2（μ-NH 2）3（NH3）10]（N3）3 <$1.25NH3的单晶。我们相信，这种新的路线可以导致新的金属叠氮化物以及主族氮化物，过渡，稀土金属仔细分解。
Beside several other applications, metal azides can be used for the synthesis of nitridophosphates and binary nitrides. Herein we present a novel synthetic access to azides: Several metals, such as main-group, transition metals, and rare-earth metals, react with silver azide in liquid ammonia as a solvent giving the corresponding metal azides. In this work Mn(N3)2, Sn(N3)2, and Eu(N3)2, as well as their ammonia complexes were synthesized for the first time through low-temperature methods. Also a simpler access to Zn(N3)2 was possible. At room temperature and the respective vapor pressure of NH3, it became possible to grow single crystals of the dinuclear holmium azide [Ho2(μ-NH2)3(NH3)10](N3)3⋅1.25NH3. We are confident that this new route could lead to novel metal azides as well as nitrides of the main-group, the transition, and the rare-earth metals upon careful decomposition.
