abstract = {A series of isostructural dinuclear 3d-4f complexes,
isolated as [CuLn(L·SMe)2(OOCMe)2(NO3)]·xMeOH (Ln = Gd 1,
Tb 2, Dy 3, and Y 4; x = 0.75–1) and comprising one
acetate and two thioether-Schiff base (L·SMe–) bridging
ligands based on 4-(methylthio)aniline and
2-hydroxy-3-methoxybenzaldehyde (HL·SMe = C15H15NO2S), was
synthesized and fully characterized. The magnetic properties
of the charge-neutral {CuLn} complexes are dominated by
ferromagnetic CuII–LnIII exchange interactions. Large-area
electron transport studies reveal that the average
conductivity of robust, self-assembled {CuLn} monolayers on
a gold substrate is significantly lower than that of common
alkanethiolates. Theoretical calculations of transmission
spectra of individual complexes 1 and 4 embedded between two
metallic electrodes show that the molecular
current–voltage (I–V) characteristics are strongly
influenced by electron transport through the Cu centers and
thus fully independent of the lanthanide ion, in excellent
agreement with the experimental I–V data for 1–4. The
β-polarized transmission indicated by calculations of 1 and
4 points out their potential as spin filters. In addition,
the reactivity of the title compound 1 with CuII in a
square-pyramidal coordination environment toward methanolate
and azide was examined, resulting in the formation of a
linear trinuclear complex, [Cu2Na(L·SMe)4]NO3·3MeOH (5),
characterized by antiferromagnetic exchange interactions
between the two copper ions.},
