Due to their applications in magnetic, optical, electronic and catalyst, polynuclear lanthanide clusters are of importance. In this part, a series of nanowheel-shaped nonanuclear lanthanide clusters,〓〓(Ln=Sm~Tm; BA=benzoylacetone), were prepared and characterized. Each complex can exist in three phases, i. e., cubic, tetragonal and triclinic.
