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(N 3 ) 2 , Sn(N 3 ) 2 , and Eu(N 3 ) 2 , as well as their ammonia complexes were synthesized for the first time through low‐temperature methods. Also a simpler access to Zn(N 3 ) 2 was possible. At room temperature and the respective vapor pressure of NH 3 , it became possible to grow single crystals of the dinuclear holmium azide [Ho 2 (μ‐NH 2 ) 3 (NH 3 ) 10 ](N 3 ) 3 ⋅1.25 NH 3 . 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.
