Sodium nitride

The effect of sodium nitride on trichloroacetonitrile in the presence of ammonium chloride was used to make tetrazole. The operation was interrupted by the medium detonating. 

Addition of water to sodium azide which had been heated strongly caused a violent reaction. This was attributed to formation of metallic sodium or sodium nitride. 

By measuring the temperature dependence of second-harmonic generation (SHG) of the neodymium laser wavelength at 1.06 pm in sodium nitride for five different radiation geometries which correspond to the five nonvanishing components of the nonlinear susceptibility tensor, Vogt etal. 3 2) could determine these tensor components and the coherence length 1 = 4 2 re the... 

Sodium is stable in nitrogen at most temperatures. Reaction, however, occurs at very high temperatures or when nitrogen is activated by electric discharge. The products are sodium azide, NaNs, and sodium nitride, NasN ... 

G. Salet showed that the gas given off is ammonia. H. Hardtung was unsuccessful in an attempt to make the nitride by heating sodium at 250°-400° in dry nitrogen. J. L. Gay Lussac and L. J. Thenard reported that a black nitride is formed when sodamide is heated, but A. W. Titherley was unable to confirm this. P. Fischer and F. Schroter prepared sodium nitride mixed with free sodium, in the apparatus illustrated diagrammatically in Fig. 11. A glass tube, A, contains a platinum... 

There are three types of giant structure - ionic, metallic and macromolecular. a Sodium nitride is an ionic compound. Draw a diagram that shows the formula of the compound, the charges on the ions and the arrangement of the valency electrons around the negative ion. 

Sodium nitride, Na3N.—The nitride is formed by submitting sodium to the action of the silent electric discharge in an atmosphere of nitrogen.4 It is decomposed by water, with energetic evolution of ammonia. Fischer and Schroter5 also claim to have prepared it, but they give no analyses or formula.

Fig. 10.3 (a) The solid state structure of Li3N consists of layers of N and Li+ ions (ratio 1 2) alternating with layers of Li+ ions the latter are arranged such that they lie over the ions. Each N centre is in a hexagonal bipyramidal (8-coordinate) environment there are two types of Li ion, those in layer 1 are 2-coordinate, and those in layer 2 are 3-coordinate with respect to the N centres (see problem 10.12 at the end of the chapter), (b) The unit cell of sodium nitride Na3N adopts an anti-Re03 structure. Colour code N, blue Li, red Na, orange. 

The classification of saline nitride implies the presence of the N ion, and as we discussed in Section 14.1, this is unlikely. However, it is usual to consider Li3N, Na3N (see Section 10.4), Be3N2, Mg3N2, Ca3N2, Ba3N2 and AIN in terms of ionic formulations. Hydrolysis of saline nitrides liberates NH3. Sodium nitride is very hygroscopic, and samples are often contaminated with NaOH (reaction 14.50).
