The area of single molecule magnetism(SMM)continues to attract much attention owing to their interesting potential applications,such as high-density data storage devices,quantum information processing,and molecular spintronic.[1] Metallacrowns(MCs)also have been reported and exhibited SMMs behavior.Furthermore,the general MCs framework also have been used as “building blocks” to produce other SMMs.[2-4] We expect to obtain series of novel SMMs from the previously reported copper(Ⅱ)-lanthanide(Ⅲ)MCs as building blocks in order to compare their magnetic properties.
