摘 要：A new 3d-4f heteronuclear complex [Fe（phen）3]2[FeDy（H2O）（tiron）3]·6H2O （1,Na2H2tiron=disodium 4,5-dihydro-xybenzene-1,3disulfonate） was synthesized by the hydrothermal reaction. The complex crystallized in the cubic system, space group P213 with the cell parameters:a=2.18786（14）nm, V=10.4727（12）nm3 , Z=4, F（000）=4720, R1=0.0493, wR2 =0.1165, S=1.05. In each [FeDy（H2O）（tiron）3]6-unit, it was revealed that the Fe3+ ion was in a FeO6 distorted trigonal anti-prism coordination polyhedron completed by six phenolate O atoms from three tiron 4- ligands, while Dy3+ in a DyO7 distorted monocapped trigonal anti-prism coordination polyhedron completed by three phenolate μ2-O atoms and three O atoms from sulfonate groups of three ligands and one O atom from water. The magnetic properties of the complex was determined in the range of 2-300K, indicating the antiferromagnetic interaction between the central DyIII-FeIII ions.
