Hydro(solvo)thermal Synthetic Strategy Towards Azido/Formato-mediated Molecular Magnetic Materials

Abstract Hydro(solvo)thermal synthesis is a widely-used method to assemble various molecular magnetic materials based on different types of ligands. This review mainly focuses on the study of the magnetochemistry of azide/formate-mediated molecule-based magnetic materials of our lab synthesized under hydro(solvo)thermal conditions in the presence of coligand, with an emphasis on anionic coligand of carboxylate. The first section gives a brief discussion of azido and formato complexes and some important principles obtained from magneto-structural correlation; hydro(solvo)thermal synthetic strategies will also be referred to and elucidated in this part. The next six sections give overviews of the main results obtained in our group in recent years, that is, azide/formate-mediated ferromagnetism, ferrimagnetism, spin canting (or weak ferromagnetism), antiferromagnetism, single-molecule magnets (SMMs) and single-chain magnets (SCMs), and metamagnetism. Finally, the conclusions and perspectives of azido/formato-mediated molecular magnetic materials will be presented. Some of the trends identified could provide new insights into the further development of this promising area.
