Nitrogen-arsenic compounds

Heteropolyacids (HPA) are the unique class of inorganic complexes. They are widely used in different areas of science in biochemistry for the precipitation of albumens and alkaloids, in medicine as anticarcinogenic agents, in industry as catalysts. HPA are well known analytical reagents for determination of phosphoms, silica and arsenic, nitrogen-containing organic compounds, oxidants and reductants in solution etc. 

In this section, syntheses of a variety of inorganic nitrogen compounds are described. The syntheses include those of triazanium chlorides alkylamino derivatives of boron, arsenic, and tin and trimeric and tetrameric boron-nitrogen ring structures as exemplified by borazine (HNBH)3.

The substance described as tetrammino-arsenie iodide, [As(NH3),]I3, is a yellow powder which loses ammonia on heating above 50° C., and at 300° C. decomposes into arsenic, nitrogen, and ammonium iodide. If the compound be cooled to 0° C. and ammonia again passed over it, a pale yellow liquid, of composition [As(NIT3)12]I3, is formed. Ilugot again obtained only the amide, As(NH2)3, on treating1 the iodide with ammonia gas.

The phosphoms azides P(N3)3, P(N3)4+, P(N3)5, and P(N3)6 have long been known (see Phosphorus-Nitrogen Compounds). More recently, the binary arsenic, antimony, and bismuth M(N3)3, the cations As(N3)4+ and Sb(N3)4+, and the arsenic and antimony M(N3)4 and M(N3)e anions have been synthesized. While the cations and binary azides are very sensitive(the bismuth compound has not been isolated), the anions, in combination with sufficiently large cations such as As(Ph)4+, are less sensitive. Attempts to prepare the As(V) and Sb(V) pentaazides resulted in explosions.

Oxidation of organoarsenic(III) compounds containing As—N bonds by chloranil or CI2 gives the corresponding arsenic(V) nitrogen compounds as shown in equations 324 and 325. ... 

The organotin derivatives of phosphorus, arsenic, antimony, and bismuth have much in common with the corresponding derivatives of nitrogen, the most obvious difference being that the nitrogen compounds are unreactive towards oxygen, whereas the others are oxidised in air ...
