title: Exploiting verdazyl radicals to assemble 2p-3d-4f one-dimensional chains.
abstract: A series of one dimensional chain complexes [Ln(hfac)3]2·[Cu(hfac)2]2·4(3pyvd)·n-C7H16 (Ln = Gd(1), Tb(2), Dy(3)) containing 2p, 3d and 4f spin carriers have been successfully synthesized and magnetically characterized where the verdazyl radicals represent the bridge linking copper(II) and lanthanide(III) ions. Rough estimation of magnetic behaviors of complex 1 revealed that the coupling between a Gd(III) ion and a radical is weakly ferromagnetic, while alternating-current susceptibilities of complexes 2 and 3 suggest no slow magnetic relaxations exist at low temperature.
