Synthesis, Characterization and properties studies of new magnetic materials

摘要

We are interested in molecular polymetallic species having high spin and nuclearities in relation to the field of so call single-molecule magnets (SMMs). The goal is to find a way to synthesis metal clusters which may have application in magnetism and nano-sciences. With this purpose, we decided to investigate the coordination chemistry of the Schiff base.Along this way we were able to create cubane-like complexes and elaborate new Single Molecule-Magnets. The idea was to use Schiff base ligands and different metals to generate high nuclear complexes. Complexation of Shift base with copper has been investigated. Tetranuclear complex with a cubane like core have been synthesised with (Sciff base), with the same base and cobalt we obtains an other single magnetic complex completely different.
