“…The redox reactions of silver azide and metals (M = Mn, Sn, Zn, Eu) require a reaction time between 9 and 10 days at À40 8C. The crystal structure of Zn(N 3 ) 2 (NH 3 ) 2 , already described, [19] was verified for the bulk material by a Rietveld refinement. In this case the reaction mixtures were intensively stirred using a magnetic stirrer when all AgN 3 is dissolved (after approximately one day).…”

A New Route to Metal Azides

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.

“…It is also possible to filter off the precipitated silver and to remove the liquid ammonia by warming to room temperature. Colorless powders of Mn(N 3 ) 2 (NH 3 ) 2 and Zn(N 3 ) 2 (NH 3 ) 2 are obtained, respectively, [5,25] as shown for manganese halides in the literature. [47] Vice versa, adding liquid ammonia to the powderous diammines results in the formation of colorless crystals of compounds 4 and 5.…”

“…[13] Diammine zinc(II) azide was synthesized and structurally characterized. [25] According to the literature, a hexaamminesodium azide was described for the system sodium azide and liquid ammonia. [26] In contrast to this report, the formation of a [Na(NH 3 ) 5 ] + cation, which has been known only from Zintl ion chemistry in form of the compounds [Na(NH 3 ) 5 ][Na(NH 3 ) 3 (P 3 H 3 )] and Na(NH 3 ) 5 RbSe 3 ·3NH 3 has been observed.…”

The synthesis of ammine metal azides is achieved through a simple route in liquid ammonia solution. Azides of silver, sodium, manganese, and zinc were obtained as ammine complexes from liquid ammonia and the solid compounds were characterized. The NH 3 solutions were investigated by means of NMR spectroscopy as well. The triamminesilver(I) azide as well as the unusual tetraamminesilver(I) 796and pentaamminesodium(I) azides are presented. The structures of the hexaamminemanganese(II) and hexaamminezinc(II) azides, which crystallize with four ammonia molecules of solvation, are elucidated. From these compounds the binary azides Mn(N 3 ) 2 and Zn(N 3 ) 2 were obtained by (careful) heating.

“…The analogous ammonia compound Zn(N 3 ) 2 ⋅2 NH 3 has been known since 1907, and is conveniently prepared by the reaction of potassium azide and zinc nitrate in liquid ammonia, as shown by Agrell and Vannerberg . In 1971, they were able to determine the single‐crystal structure, which displays a molecular assembly of tetrahedrally coordinated zinc centers in the solid state ,.…”

Pure, solvent-free Zn(N ) was prepared by reaction of diethyl zinc and hydrazoic acid in aprotic solvents. The single-crystal structure determination, along with the comprehensive characterization of α-Zn(N ) and two metastable polymorphs, could be achieved for the first time. Since these data disagree in large parts with the known, previously reported values, all previous syntheses of Zn(N ) , and for comparison Zn(N ) ⋅2.5 H O and Zn(OH)N were reinvestigated, indicating that some of the earlier work has to be revised.
