Iodide ammoniated

The pure tribromide and triodide are unknown but their ammoniates have been prepared by the action of the appropriate halogen on ammonia. The tribromide, NBr bNUj, is a purple solid which decomposes explosively above 200K. The iodide, Nl3. NH3, is a black explosive crystalline solid, readily hydrolysed by water. 

Mercuric chloride is widely used for the preparation of red and yellow mercuric oxide, ammoniated mercury/7(9/USP, mercuric iodide, and as an intermediate in organic synthesis. It has been used as a component of agricultural fungicides. It is used in conjunction with sodium chloride in photography (qv) and in batteries (qv), and has some medicinal uses as an antiseptic. 

The enthalpy of solution of the ammoniate LaI3-6NH3 in liquid ammonia at 25°C is -178.5 kJ mol-1. This value is close to that at infinite dilution, for it was determined at a concentration of Lal3 in the product solution of only 1 in 18,500 (224). Comparisons of this value with those for other iodides, or for aqueous media, are complicated by the fact that the ammoniate rather than anhydrous Lal3 was used for this calori-...

Solutions of alkali metals in ammonia have been the best studied, but other metals and other solvents give similar results. The alkaline earth metals except- beryllium form similar solutions readily, but upon evaporation a solid ammoniate," MINI-lj),. is formed. Lanthanide elements with stable + 2 oxidation states (europium, ytterbium) also form solutions. Cathodic reduction of solutions of aluminum iodide, beryllium chloride, and tetraalkylammonium halides yields blue solutions, presumably containing Al, 3e Be", 2e and R4N, e respectively. Other solvents such as various amines, ethers, and hexamethylphosphoramide have been investigated and show some propensity to form this type of solution. Although none does so as readily as ammonia, stabilization of the cation by complexation results in typical blue solutions...

OTHER COMMENTS inorganic salts of mercury, such as ammoniated mercuric chloride or mercuric iodide have been used in skin lightening creams mercuric chloride has been used as a topical antiseptic or disinfectant agent mercuric sulfide and mercuric oxide are used as pigments in paints mercuric sulfide is also used as a pigment for tattoos some inorganic mercury compounds are also used in fungicides. 

If the explanation of the relation between alcohols and ethers is accepted, it becomes easier to understand alkyl compounds and their reactions in general. They fall into the same class as the ammoniates and the hydrates, and may be called olefinates. Alcohol and ether are water olefinated to different degrees. Their constitutions may be expressed as follows (01 olefin) Alcohol, Ol.HOH ether, Oh.HOH alkyl iodide, Ol.HI ethyl sulfuric acid, En.H2S04 etc. The reaction for the formation of ethyl ether may be expressed as follows ...
