摘要：

Six novel mu-oxamido heterometal binuclear complexes have been synthesized and characterized, namely Cu(oxae)Ln(L)(2)(ClO4)(3), where oxae denotes the N,N'-bis(2-aminoethyl) oxamido dianion, L denotes 1,10-phenanthroline (abbreviated as phen) and Ln represents Eu, Gd, Tb, Dy, Ho or Er. The magnetic susceptibility of Cu(oxae)Gd(phen)(2) (ClO4)(3) was measured over the range 4-300 K and the observed data were successfully simulated by an equation based on the spin Hamiltonian operator (($) over cap H = -2J ($) over cap S-1.($) over cap S-2), giving the exchange integral J(Cu-Gd) = -0.62 cm(-1). This indicates a weak antiferromagnetic interaction between the copper(II) and godolinium(III) ions.
