Field-Induced Dysprosium Single-Molecule Magnet Based on a Redox-Active Fused 1,10-Phenanthroline-Tetrathiafulvalene-1,10-Phenanthroline Bridging Triad.

ABSTRACT: Tetrathiafulvalene and 1,10-phenanthroline moieties present, respectively remarkable redox-active and complexation activities. In this work, we investigated the coordination reaction between the bis(1,10-phenanthro[5,6-b])tetrathiafulvalene triad (L) and the Dy(hfac)₃·2H₂O metallo precursor. The resulting {[Dy₂(hfac)₆(L)]·CH₂Cl₂·C₆H₁₄}₃ (1) dinuclear complex showed a crystal structure in which the triad L bridged two terminal Dy(hfac)₃ units and the supramolecular co-planar arrangement of the triads is driven by donor-acceptor interactions. The frequency dependence of the out-of-phase component of the magnetic susceptibility highlights three distinct max
