Summary
Ten novel μ-oxamido trinuclear complexes, namely Cu2−(oxae)2Ln(ClO4)3 (Ln = Y, Pr, Sm, Eu, Gd, Tb, Dy, Ho, Er and Yb), where oxae donotes the N,N′-bis(2-aminoethyl)-oxamido dianion, were prepared and characterized. The magnetic susceptibility of Cu2(oxae)2Gd(ClO4)3 was measured over the 4–300 K range and the observed data were successfully simulated by an equation based on the spin Hamiltonian operator \([\hat H = - 2J(\hat S_{Gd} \cdot\hat S_{Cu_1 } + \hat S_{Gd} \cdot\hat S_{Cu_2 } ) - 2J'(\hat S_{Cu_1 } \cdot\hat S_{Cu_2 } )]\). The exchange integrals J (Gd-Cu) and J′ Gd-Cu were found to be 2.37 and −0.71cm-1, respectively, indicating that very weakly ferromagnetic spin-exchange interaction operates between copper(II) and gadolinium(III) ions.
