They are typically denser than water due to the presence of chlorine, which has a high atomic weight. Category: chlorides-buliding-blocks.
Fernando, Nathalie K.;Cairns, Andrew B.;Murray, Claire A.;Thompson, Amber L.;Dickerson, Joshua L.;Garman, Elspeth F.;Ahmed, Nayera;Ratcliff, Laura E.;Regoutz, Anna research published 《 Structural and Electronic Effects of X-ray Irradiation on Prototypical [M(COD)Cl]2 Catalysts》, the research content is summarized as follows. X-ray characterization techniques are invaluable for probing material characteristics and properties, and have been instrumental in discoveries across materials research. However, there is a current lack of understanding of how X-ray-induced effects manifest in small mol. crystals. This is of particular concern as new X-ray sources with ever-increasing brilliance are developed. In this paper, systematic studies of X-ray-matter interactions are reported on two industrially important catalysts, [Ir(COD)Cl]2 and [Rh(COD)Cl]2, exposed to radiation in X-ray diffraction (XRD) and XPS experiments From these complementary techniques, changes to structure, chem. environments, and electronic structure are observed as a function of X-ray exposure, allowing comparisons of stability to be made between the two catalysts. Radiation dose is estimated using recent developments to the RADDOSE-3D software for small mols. and applied to powder XRD and XPS experiments Further insights into the electronic structure of the catalysts and changes occurring as a result of the irradiation are drawn from d. functional theory (DFT). The techniques combined here offer much needed insight into the X-ray-induced effects in transition-metal catalysts and, consequently, their intrinsic stabilities. There is enormous potential to extend the application of these methods to other small mol. systems of scientific or industrial relevance.
