We reported that two cyclic 3d-4f tetranuclear compounds [CuIILLnIII(hfac)2]2 (Ln ) Tb, Dy) assume a SMM behavior. The present study demonstrates that the synthesis of the d-f polynuclear molecule is a very promising approach to SMMs. There are several advantages: (1) the d-f polynuclear molecule can be easily synthesized by the assembly reaction of the d-component exhibiting a donor coordination ability and the f-component exhibiting an acceptor coordination ability, (2) the high-spin ground state can be generated by a smaller number of metal ions than the d polynuclear complex, and (3) the molecular magnetic anisotropy is easily derived from the f-component.

Abstract
We reported that two cyclic 3d-4f tetranuclear compounds [CuIILLnIII(hfac)2]2 (Ln ) Tb, Dy) assume a SMM behavior. The present study demonstrates that the synthesis of the d-f polynuclear molecule is a very promising approach to SMMs. There are several advantages: (1) the d-f polynuclear molecule can be easily synthesized by the assembly reaction of the d-component exhibiting a donor coordination ability and the f-component exhibiting an acceptor coordination ability, (2) the high-spin ground state can be generated by a smaller number of metal ions than the d polynuclear complex, and (3) the molecular magnetic anisotropy is easily derived from the f-component.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
