Inorganic solid-state compounds, synthesis

The use of organic molecules in the synthesis of zeotype solids is an especially interesting preparative method for extended inorganic solid materials. Organic molecules cannot survive the harsh conditions of the classical high-temperature route involving reaction of the components in the solid state. Structure-directed synthesis thus belongs to the "soft chemistry" routes for the preparation of solid-state compounds [12, 13]. 

We have been interested in developing new routes to mesostructured metal sulfides. Our approach capitalizes on well-established solution condensation reactions that can transform discrete, soluble metal thiolate species into solid-state metal sulfide compounds. Here we wish to describe the use of (NH4)2WS4 as a precursor material in the synthesis of three mesostructured tungsten suldifes with the inorganic walls that consist of continuous WS3 chains and WS2. 

IV,N,N -Tris(trimethylsilyl)amidines have been used recently as precursors for a number of inorganic heterocycles and metallacycles,1 some of which are being studied in light of their unusual solid state properties2. Boere et al. reported the synthesis of several aryl-substituted persilylated benzamidines and the related compound /V,N,N, N",N",Ar" -hexakis(trimethylsilyl)-l,4-benezenedicarboximidamide (hereafter referred to as HBDA) 3 the present syntheses, which are generally based on the same reaction of an aryl-substituted carbonitrile with lithium bis(trimethylsilyl)amide, offer more facile routes to representative mono- and polyfunctional carboximidamides (i.e., amidines) as well as the prototypal derivative N,N,N -tris(trimethyl-silyl)formimidamide.4 As before, the crystalline diethyl ether adduct of lithium bis(trimethylsilyl)amide5 is favored over the nonsolvated amide in these syntheses the preparation of the diethyl ether adduct is also described here.

Hybrid framework compounds, including both metal-organic coordination polymers and systems that contain extended inorganic connectivity (extended inorganic hybrids), have recently developed into an important new class of solid-state materials. We examine the diversity of this complex class of materials, propose a simple but systematic classification, and explore the chemical and geometrical factors that influence their formation. We also discuss the growing evidence that many hybrid frameworks tend to form under thermodynamic rather than kinetic control when the synthesis is carried out under hydrothermal conditions. Finally, we explore the potential applications of hybrid frameworks in areas such as gas separations and storage,...

Structure solution from X-ray powder diffraction began as a means of characterising inorganic products of solid state synthesis [36] but has been more widely used in recent years for the study of organic compounds [34b, 37], particularly of pharmaceutical importance. There have been some notable recent successes in the area of organometallic compounds [38], but structure determination of coordination framework materials is very much in its infancy [39].
