📖 Fluorinated and Fluorine-Free Coordination Polymers. Alkaline Earth Metals, Mechanochemical Synthesis, ab initio Structures Determination, and Characterization.

Increasing concern towards environmental issues motivates researchers to develop synthesis methods that are eco-friendly such as mechanochemistry which is established as green and rapid synthesis route for preparing materials. Coordination polymers are functional materials consisting of metal nodes bridged by functionalized organic linkers. The presence of fluorine improves the water stability of resulting compounds. Alkaline earth metals are handy for aqueous preparations, which open doors for further applications. Also, the abundant and biocompatibility of AE ions promise for constructing economical and non-toxic CPs with interesting properties. These materials are synthesized under solvothermal conditions. In this work, the mechanochemical syntheses are employed as a rapid and green method for synthesizing a series of coordination polymers. The fluorinated materials obtained by milling are compared to their fluorine-free counterparts under the same conditions. The crystal structures of materials obtained by milling are determined ab initio from powder X-ray diffraction data. The resulting compounds after milling are systematically investigated by different analytical methods.
