“…50 And, third, there is the propensity for guest intercalation between layers or chains. This type of behaviour has long been known to occur for Ni(CN) 2 , 51 and can induce visible colour changes during the switching between disordered and fully crystalline states in response to guest binding. 42…”

It is increasingly apparent that many important classes of molecular framework material exhibit a variety of interesting and useful types of structural disorder. This tutorial review summarises a number of recent efforts to understand better both the complex microscopic nature of this disorder and also how it might be implicated in useful functionalities of these materials. We draw on a number of topical examples including topologically-disordered zeolitic imidazolate frameworks (ZIFs), porous aromatic frameworks (PAFs), the phenomena of temperature-, pressure- and desorption-induced amorphisation, partial interpenetration, ferroelectric transition-metal formates, negative thermal expansion in cyanide frameworks, and the mechanics and processing of layered frameworks. We outline the various uses of pair distribution function (PDF) analysis, dielectric spectroscopy, peak-shape analysis of powder diffraction data and single-crystal diffuse scattering measurements as means of characterising disorder in these systems, and we suggest a number of opportunities for future research in the field.

Seven complex compounds exhibiting the compositions Ni(en)3Ni(CN),'H20 (I), Ni(en)aNi(CN)4 (II), ct-Ni(en)2Ni(CN)4 (III), Ni(en)Ni(CN)4 9 2H20 (IV), Ni(en)Ni(CN)~ (V), Ni(en)2Ni(CN)4-2.5H20 (VI) and fl-Ni(en)2Ni(CN)4 (VII) were prepared from the system Nien-[Ni(CN)4]2--H20. These compounds were examined by the methods of infrared spectroscopy, X-ray powder diffractometry, UV-VIS reflectance spectroscopy, and also by the measurement of magnetic moments. The thermal stability, the stoichiometry of thermal decomposition and the mutual transformations were investigated with a derivatograph. The reactions proceeding according to the following schemes were observed if the system was heated to appropriate temperature:

Self‐Assembling Frameworks: Beyond microporous oxides

For inorganic chemists, the 1990s have brought a blossoming, both of a large field of ordered solid-state structure synthesis and a large number of words to describe it. Organized, functional nanostructures are made using supramolecular chemistry; molecular recognition guides selfassembly or self-organization; molecular patterning and templating are tools for directed synthesis."'21 All of these words reflect a desire, on the part of the chemist, to deliberately control, to design, the synthesis of a particular solid-state structure.In order to achieve the goals of advanced materials science which are to create materials for quantum electronics, nonlinear optics, photonics, chemoselective sensing, size-and shape-selective electrocatalysis and redox processes, among others, we wish to build-in function by controlling form. Within the field of crystalline, microporous "zeotype" materials, there has been a significant change reflected in the language used to describe the work. Natural and synthetic zeolites were discovered, where currently we design, or "create and invent""] novel open framework types. The diversity of non-oxide open-framework materials, that we "design" today are not materials "waiting to be discovered".The object of self-assembly is to put together a set of reagents, molecules, with matching functional groups and or templates, such that they are compelled to join together in a predefined way. This is, of course, easier said than done! The challenge, then, is to characterize and to predict the modes of formation of the desired materials, in this case crystalline, non-oxide, porous, inorganic and organometallic frameworks. The empirical approach has been to synthesize as many structures in as many systems with as many topologies as possible, in order to fully explore and understand all the tools at hand, and so to develop the skill to predefine the structure-property-function relationship.
