Crystal structure inorganic acids

Nitric acid is one of the three major inorganic acids in the chemical industry. Its structural parameters in the gaseous state are shown in Fig. 15.2.2(d). The crystals of nitric acid monohydrate consist of H30+ and N0, which are connected by strong hydrogen bonds. In the acid salts, HNO3 molecules are bound to nitrate ions by strong hydrogen bonds. For example, the structures of [H(N03)2r in K[H(N03)2] and [H2(N03)3] in (NH4)H2(N03)3 are as follows ...

Similarly, X-irradiation of a single crystal of methylenediarsonic acid produced the radical (0H)(0)AsCH2As(0)(0H)2 whose structure is practically the same as that obtained for the phosphorus analogue . The inorganic radicals AsO-3 and... 

A third point to be noted from table 8.07 is that among the compounds with the perovskite structure are many titanates niobates 4 stannates , etc., which would normally be regarded as inorganic salts. Structurally, however, there is no justification for this view. We shall later find that in the true salts of inorganic acids finite complex anions have a discrete existence in the crystal structure in calcium carbonate, for example, anions C032 are clearly recognizable and the structure as a whole is built up of these anions and of Ca2+ cations arranged in a manner very...
