Magnetic Bistability in the Crystaline Fullerene Radical Salt

Compounds with magnetic bistability is highly attractive for the construction of switches,thermal sensors,information-storage media and memory devices.Herein,we report a crystalline fullerene radical anion salt[Na(THF)5]C60(1),obtained by the reduction of C60 with Na in solution,which exhibits magnetic bistability accompanied with one magnetostructural transition,giving low temperature(LT),high temperature(HT)phases and a metastable phase.Fullerene radical anions(C60·-)in the structure were found arranged into a three-dimensional close-packed honeycomb subnetwork with hollow channels occupied by complex cations[Na(THF)s]+as spacers.The magnetic bistability is attributed to structural transitions as the LT-IT phase transition was associated with the orientational disorder of fullerene anions and the distortion of the complex cations[Na(THF)5]+in the 3D packing of fullerene anions.
