  An extensive series of tetranuclear Cu(2)(II)Ln(2)(III) complexes [Cu(II)LLn(III)(hfac)(2)](2) (with Ln(III) being all lanthanide(III) ions except for the radioactive Pm-III) has been prepared in order to investigate the nature of the Cu-II-Ln(III) magnetic interactions and to try to answer the following question: What makes the (Cu2Tb2III)-Tb-II and (Cu2Dy2III)-Dy-II complexes single molecule magnets while the other complexes are not? All the complexes within this series possess a similar cyclic tetranuclear structure, in which the Cu-II and Ln(III) ions are arrayed alternately via bridges of ligand complex ((CuL)-L-II). Regular SQUID magnetometry measurements have been performed on the series. The temperature-dependent magnetic susceptibilities from 2 to 300 K and the field-dependent magnetizations from 0 to 5 T at 2 K have been measured for the Cu(2)(II)Ln(2)(III) and Ni(2)(II)Ln(2)(III) complexes, with the Ni(2)(II)Ln(2)(III) complex containing diamagnetic Ni-II ions being used as a reference for the evaluation of the Cu-II-Ln(III) magnetic interactions. These measurements have revealed that the interactions between Cu-II and Ln(III) ions are very weakly antiferromagnetic if Ln = Ce, Nd, Sm, Yb, ferromagnetic if Ln = Gd, Tb, Dy, Ho, Er, Tm, and negligible if Ln = La, Eu, Pr, Lu. With the same goal of better understanding the evolution of the intramolecular magnetic interactions, X-ray magnetic circular dichroism (XMCD) has also been measured on (Cu2Tb2III)-Tb-II, (Cu2Dy2III)-Dy-II, and (Ni2Tb2III)-Tb-II complexes, either at the L- and M-edges of the metal ions or at the K-edge of the N and O atoms. Last, the (Cu2Tb2III)-Tb-II complex exhibiting SMM behavior has received a closer examination of its low temperature magnetic properties down to 0.1 K. These particular measurements have revealed the unusual very slow setting-up of a 3D order below 0.6 K.

  A cyclic cylindrical 3d-4f tetranuclear structure, in which the 3d and 4f magnetic ions are arrayed alternately, has been found to be a suitable molecular design to produce a large magnetic moment and large magnetic anisotropy. Complexes 3-10 with the chemical formula [MLLn(hfac)(2)](2) ((M-II, Ln(III)) = (Cu, Eu) (3), (Cu, Gd) (4), (Cu, Tb) (5), (Cu, Dy) (6), (Ni, Eu) (7), (Ni, Gd) (8), (Ni, Tb) (9), (Ni, Dy) (10)) have been synthesized, where H3L = 1-(2hydroxybenzamido)-2-(2-hydroxy-3-methoxybenzylideneamino)ethane and Hhfac = hexafluoroacetylacetone. The powder X-ray diffractions and FAB-mass spectra demonstrated that these complexes assume a similar tetranuclear structure. The crystal structures of 4 and 5 showed that each complex has a cyclic cylindrical tetranuclear Cu(2)(II)Ln(2)(III) structure, in which the Cull complex functions as a "bridging ligand-complex" to two adjacent Ln(III) ions. The temperature-dependent magnetic susceptibilities from 2 to 300 K and the field-dependent magnetizations at 2 K from 0 to 5 T have been measured for four pairs of Cu(2)(II)Ln(2)(III) and Ni(2)(II)Ln(2)(III), in which compound Ni(2)(II)Ln(2)(II) containing diamagnetic Ni-II ion was used as the reference complex to evaluate the Cu-II-Ln(III) magnetic interaction. Comparison of the magnetic properties of the CU(2)(II)Ln(2)(III) complex with those of the corresponding Ni(2)(II)Ln(2)(III) complex showed that the magnetic interaction between Cu-II and Eu-III ions is weakly ferromagnetic and that between Cu-II and either of Gd-III, Tb-III, and Dy-III ions is ferromagnetic. Complex (Cu2Gd2III)-Gd-II, 4, has an S = 8 spin ground state, due to the ferromagnetic spin coupling between S-Gd = 7/2 and S-Cu = 1/2 with coupling constants of J(1) = +3.1 cm(-1) and J(2) = +1.2 cm(-1). The magnetic measurements showed that compounds 5 and 6, Cu(2)(II)Ln(2)(III) (Ln(III) = Tb, Dy), exhibit large magnetic moments and large magnetic anisotropy due to the Ln(III) ion.

  We report now the first single molecule magnet (SMM) consisting of d-f elements. The present study demonstrates that the synthesis of the d-f polynuclear molecule is a very promising approach to SMMs. (1) The d-f polynuclear molecule can be easily synthesized by the assembly reaction of the d-component and the f-component, (2) the high-spin ground state can be generated by a smaller number of metal ions than the d complex, and (3) the molecular magnetic anisotropy is easily derived from the f-component.
