Redox shield enfolding a magnetic core

Ferrocenyl betadiketones were reacted with hydrated lanthanide trihalides in presence of a base to yield red color solids, whose structures were characterized by single crystal X-ray diffraction technique. Structural analysis revealed the formation of nona- and tetranuclear lanthanide oxo-hydroxo cl...
