Protein crystaUographers have greater responsibUity for experimental work than computational chemists. The former scientists, for example. [Pg.79]

Zeohtes may be considered to be made up of frameworks consisting of cornersharing silicate and aluminate tetrahedra. Whereas pure sihca frameworks are electrically neutral, the substitution of trivalent aluminium for tetravalent sihcon imparts a negative charge to the framework that has to be balanced by positively charged extra-framework cations. The general formula of a zeolite is therefore  [Pg.11]

For some zeolites with high aluminium contents, such as zeolite A or X, however, the acid form is unstable. [Pg.13]

This is the first monograph that was devoted to structure, chemistry and use of zeolites. It reviews zeolite synthesis to 1973, gives a detailed structural description of synthetic and mineral zeolites, illustrates their physical properties and describes applications. [Pg.2793]

The enormous amount of research at the interface between physical and structural chemistry has been expertly reviewed recently by Schmalzried in a book about chemical kinetics of solids (Schmalzried 1995), dealing with matters such as morphology and reactions at evolving interfaces, oxidation specifically, internal reactions (such as internal oxidation), reactions under irradiation, etc. [Pg.46]

Diazenes of the type REN=C(R )N=NC(R )=NER have a rich structural chemistry. The selenium derivatives 15.11a,b display a cis,trans,cis conformation with two short l,5-Se N contacts (2.65 A). Several sulfur analogues, e.g., 15.1c, have the same structure, but a different cis,trans,cis conformer 15.12 with two 1,4-S N contacts (2.83 A) has also been characterized. A third type of diazene is the trans,trans,trans isomer 15.13a,b with no intramolecular short contacts. ... [Pg.296]

This is larger than the corresponding value for Li (57 kJ mol" ) but substantially smaller than the value for F (333kJmol" ). The hydride ion H" has the same electron configuration as helium but is much less stable because the single positive charge on the proton must now control the 2 electrons. The hydride ion is thus readily deformable and this constitutes a characteristic feature of its structural chemistry (see p. 66). [Pg.37]

Boron (like silicon) invariably occurs in nature as 0X0 compounds and is never found as the element or even directly bonded to any other element than oxygen. The structural chemistry of B-O compounds is characterized by an extraordinary complexity and diversity which rivals those of the borides (p. 145) and boranes (p. 151). In addition, vast numbers of predominantly organic compounds containing B-O are known. [Pg.203]

The phase relations, stoichiometry and structural chemistry of the metal borates have been extensively studied because of their geochemical implications and technological importance. Borates are known in which the structural unit is mononuclear (1 B atom), bi-, tri-, tetra- or penta-nuclear, or in which there are polydimensional networks including glasses. The main structural principles underlying the bonding in crystalline metal borates are as follows " ... [Pg.205]

F. Liebau, Silicon, element 14, in K. H. Wedepohl (ed.). Handbook of Geochemistry, Vol. 11-2, Chap. 14, Springer-Verlag, Berlin, 1978. F. Liebau, Structural Chemistry of Silicates, Springer-Verlag, Berlin, 1985, 347 pp. [Pg.347]

The structural chemistry of the Group 14 elements affords abundant illustrations of the trends to be expected from increasing atomic size, increasing electropositivity and increasing tendency to form compounds, and these will become clear during the more detailed treatment of the chemistry in the succeeding sections. The often complicated stereochemistry of compounds (which arises from the presence of a nonbonding electron-pair on the metal) is... [Pg.374]

The structural chemistry of Sn halides is particularly complex, partly because of the... [Pg.377]

Many of the most important naturally occurring minerals and ores of the metallic elements are sulfides (p. 648), and the recovery of metals from these ores is of major importance. Other metal sulfides, though they do not occur in nature, can be synthesized by a variety of preparative methods, and many have important physical or chemical properties which have led to their industrial production. Again, the solubility relations of metal sulfides in aqueous solution form the basis of the most widely used scheme of elementary qualitative analysis. These various more general considerations will be briefly discussed before the systematic structural chemistry of metal sulfides is summarized. [Pg.676]
