Applying the Mechanochemical Reaction of Cation Exchange for Green Synthesis of an Organometallic Coordination Polymer Nanofibers

Nanostructures of ZnBPDH2On 1, H2BPD 1,1´-biphenyl-2,2´-dicarboxylic acid supramolecular polymer were synthesized by the sonochemical process. The solid-state conversion of compound 1 nanostructures to nanofibers of Ag2BPDn 2 coordination polymer was investigated by cation exchange reaction of compound 1 with AgNO3. X-ray diffraction XRD analyzes and thermogravimetric and differential thermal analyses TG-DTA have shown that this conversion is irreversible. Consideration the crystal structure of these two compounds, which were reported previously, shows that during this process, the ZnO4 coordination sphere in 1 changed to AgO3Ag2˙˙˙C6 in 2, thus an organometallic compound was synthesized during this solid-state mechanochemical reaction.
