“…This in turn is determined from the standard heats of formation in kJ mol À1 of ZnO (c) (À348.3), Zn (g) (130.2), and O (g) (246.8). 239 We note that a study of bond energies in solid oxides showed that, per mol of O, bond energies to a given metal were closely constant for a variety of ternary, quaternary, etc. compounds and did not depend on coordination number (thus for one Mg forming four or six or eight bonds to oxygen to total bond energy is the same; i.e.…”

This critical review presents a comprehensive study of transition-metal carboxylate clusters which may serve as secondary building units (SBUs) towards construction and synthesis of metal-organic frameworks (MOFs). We describe the geometries of 131 SBUs, their connectivity and composition. This contribution presents a comprehensive list of the wide variety of transition-metal carboxylate clusters which may serve as secondary building units (SBUs) in the construction and synthesis of metal-organic frameworks. The SBUs discussed here were obtained from a search of molecules and extended structures archived in the Cambridge Structure Database (CSD, version 5.28, January 2007) which included only crystals containing metal carboxylate linkages (241 references).

“…Finally, the determination of the solubility product for the endrnember rhodochrosite, KMnC0 3 ' seems to be problematic, and a number of values for this parameter can be fOl l lld in the literature. Some of the KMnC0 3 values reported are: 10-1 0 .99 (Garr els et al, 1960); 10-1 0 62 (Wagman et al, 1982);10-105510- (Jolmson, 1982 and 10-94 3 (Mc Beath et al, 1998). It is clear that this lack of agreement with respect to the precipitation behaviour in the :Mn-Ca-C03-H 2 0 SS-AS system makes it difficult to propose a consistent thermodynamic model.…”

Abstract-This paper deals with the growth behaviour of the Mn-Ca-C0 3 -H 2 0 solid solution-aqueous solution system on calcite {1O I 4} surfaces. This system represents a model example, which allows us to study the effect of a number of controlling factors on the crystallisation: (1) the supersaturation function, (3(x), and nucleation rate function, J(x), for the Mn-Ca-C0 3 -H 2 0 system, (2) the relationship of such functions to the molecular scale growth mechanisms operating on growing surfaces, and (3) the surface structure of the calcite {1O I 4} faces. In situ atomic force microscopy (AFM) growth experiments revealed a wide variety of surface phenomena, such as the transition between growth mechanisms, anisotropic changes in the step rates, and the influence of the Mn-bearing newly formed surface on subsequent growth (step stoppage followed by the formation of two-dimensional nuclei and the reproduction of the original calcite {1014} surface microtopog raphy). These phenomena result from the interplay between the controlling parameters and are explained in those terms.

Thermodynamic data for the different species were taken from Hem (1976), Wagman et al (1982), Smith and Martell (1976), and Truesdel and lones (1974). Figure 4a shows the evolution of both pH and saturation states, calculated for a hypothetical situation in which no nu cleation of cerussite occurs, as a function of the amount of dissolved phosgenite in pure water.…”

Abstract-The dissolution-reprecipitation reaction of phosgenite (Pb2CI2C03) to cerussite (PbC03) has been observed in situ in a fluid cell of an atomic force microscope (AFM). The (00 I) face of phosgenite, in contact with static carbonated aqueous solutions, rapidly begins to dissolve. AFM observations show that dissolution occurs by generation and spread of square-shaped etch pits with sides parallel to (I 10) directions. The dissolution of the (110) steps is isotropic and the etch pits therefore remain square shaped during the dissolution process, as dictated by the existence of a fourfold axis perpendicular to the phosgenite (00 I) face. Two types of (110) etch pits were found: short-lived shallow pits, of one unit cell depth (8.8 A), and deep pits, which rapidly reach depths between 10 and 60 nrn. A few minutes after the dissolution begins, only the deep pits remain and subsequent dissolution of the phosgenite (001) surface proceeds by increasing their width and depth. The increase of Pb 2 + and CO�-concentration in the aqueous solution as a consequence of the dissolution sharply increases the supersaturation for PbC03. As a result, after a certain incubation time, cerussite crystals nucleate on the phosgenite (001) surface and a coupled process of dissolution-crystallisation starts. Cerussite crystals, which grow by a spiral-growth mechanism, distort the concentration field around them. As a consequence, phosgenite dissolution is accelerated in the proximity of such growing cerussite individuals and both the fonnation of new deep etch pits and the development of irregular dissolution fronts are observed. Further phosgenite dissolution leads to an increase of cerussite nucleation and growth rates, in such a way that this dissolution-crystallisation phenomenon can be considered as an autocatalytic process.
