Various compounds have been prepared by solvothermal reactions metals, metal oxides, chalcogenides, - ° nitrides, - -" phosphides, open-framework structures, - oxometalate clusters, - organic-inorganic hybrid materials, - - and even carbon nanotnbes. - Most of the solvothermal products are nano- or microparticles with well-defined morphologies. The distribution of the particle size of the prodnct is nsnally qnite narrow, and formation of monodispersed particles is freqnently reported. - When the solvent molecules or additives are preferentially adsorbed on (or have a specific interaction with) a certain surface of the products, growth of the surface is prohibited and therefore products with unique morphologies may be formed by the solvothermal reaction. - - Thus nanorods, wires, tnbes, and sheets of various types of products have been obtained solvothermally. 

A very wide range of solid state NMR experiments is therefore available for the study of the structural chemistry of microporous framework solids. Some of these are listed in Table 3.2, together with a summary of the information they give. In this chapter I will discuss the application of solid state NMR spectroscopy to the elucidation of the structural chemistry of zeolites, other inorganic molecular sieves and organic-inorganic hybrids.
