摘要Tell new mu -oxamido-bridged copper(II)-lanthanide(III) heterobinuclear complexes described by the overall formula Cu(Br(4)Obbz)Ln(phen)(2)NO3 (Ln = Y, La, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er), where Br(4)obbz denotes the oxamido-N,N'-bis(3,5-dibromobenzoato) and phen represents 1,10-phenanthroline, have been synthesized and characterized by the elemental analyses, magnetic moments (at room temperature), molar conductivity measurements and spectroscopic (IR, UV, ESR) studies. The temperature dependence of the magnetic susceptibility of Cu(Br(4)obbz)Gd(phen)(2)NO3 complex was measured over the range 4.2-300 K. The least-squares fit of the experimental susceptibilities based on the spin Hamiltonian operator, (H) over cap=-2J (S) over cap (1).(S) over cap (2), yielded J= +3.7 cm(-1). This result indicates the presence of a weak ferromagnetic spin-exchange interaction between Gd(III) and Cu(II) ions.
