| Abstract: Four novel binuclear rare earth Ln(Ⅲ) complexes containing the dianion of phthalic acid as bridging ligand have been synthesized, namely [Ln2(Phth) (NO2-phen)4](ClO4)4·xH2O(Ln= Gd, Tb, Ho, Er, NO2-phen= 5-nitro-1,10-phenantroline, Phth=dianion of phthalic acid). They have been characterized by elemental analyses, IR, electronic spectra, ESR and conductances. Variable-temperature magnetic susceptibility (4～300K) of complexes of [Gd2(Phth)(NO2-phen)4](ClO4)4·4H2O has been determined. A satisfactory fit to theoretical curve derived from spin Hamiltonian operator (H=-2JS1·S2) was obtained by least squares method. The exchange interaction parameters are J=-2.18cm-1, g= 2.81 and the agreement factor F=8.0×10-3 indicating the existence of a weak antiferromagnetic spin exchange interaction between the rare earth ions in the complex. |
