摘要

The employment of N-salicylidene-o-aminophenol in 4f-metal cluster chemistry has led to a family of {Ln(7)} clusters with a new core topology that comprises two {Ln(4)} butterflies sharing a common metal vertex; the {Dy-7} derivative exhibits slow magnetization relaxation whereas all heptanuclear compounds show ligand-centred blue-green emissions.
