![]() ![]() Hopefully, the strength of ab initio powder XRD structure elucidation with the few cases shown in this Perspective will encourage members of this field of research to exploit this technique to make further progress in MOF chemistry. The reported cases are challenging structure solution examples carried out by direct-space strategy using powder XRD data, and show that ab initio powder XRD structure solution is a powerful technique that allows many chemical reactions whose products cannot be carried out by single crystal X-ray analysis to be understood. Examples of microcrystalline MOFs obtained by solvothermal methods, synthesized by instant synthesis and mechanochemical methods and products obtained after solid-state reactivity are highlighted. X-radiation, discovered in 1895, was the key to understanding. In this article, a short overview of crystal structure solution from powder XRD and how this technique has been applied in the structure solution of MOFs using direct-space strategy is given. 12 X-ray Diffraction and Mineral Analysis. Unfortunately, structure solution from powder XRD data is more complicated than that from single crystal XRD data. In such cases, structure elucidation of MOFs must be carried out using ab initio powder XRD analysis. Moreover, X-ray diffraction (XRD) is an essential technique in the analysis of shale rock. Also, gas, temperature, and solvent induced reactions render single crystals unsuitable for single crystal XRD. The D2 PHASER is a desktop diffractometer for all X-ray powder. In MOF synthesis, rather often the products of certain synthetic approaches such as fast crystallization or mechanochemical reactions are obtained as powders. (pXRD) Powder XRD is mainly used for structural analysis of microcrystalline solid materials or powder samples. Sadly, it often occurs that it is not possible to grow crystals of enough quality for single crystal XRD analysis. Single crystal X-ray diffraction is the most reliable technique for the 3D description of the atomic arrangement of a crystalline material, but it needs a suitable single crystal both in size and in quality. Rigaku SmartLab, Automated Multipurpose x-ray Diffractometer, is an x-ray diffraction system (including thin film analysis system) equipped with a high-accuracy. Structure–function relationship properties in MOFs is a key step to understand the potential of a material for its applications in advanced technologies, which can be only understood if full structure determination is carried out. Metal organic frameworks (MOFs), also known as coordination polymers/networks, have experienced a rapid upsurge in the last 20 years in part due to the precise visualization of their atomic arrangement in the solid state. ![]()
