Ln2O3、硝酸铁、邻菲罗啉和钛铁试剂(tiron)通过水热法自组装合成了2个异质同晶的3d-4f杂核配合物[Fe(phen)3]2[FeLn(H2O)(tiron)3]·6H2O,其中,Ln=HoⅢ(1)和YbⅢ(2).X-射线单晶衍射分析表明,晶体属立方晶系,P2,3空间群.3个tiron4-配体利用酚氧桥联Ln3+和Fe3+形成具有C3对称性的[FeLn(H2O)(tiron)3]6-异双核配位单元,其中七配位的Ln3+呈现一种畸变的单帽反三棱柱配位构型.配阳离子[Fe(phen)3]3+通过phen-phen之间的π-π相互作用和与配阴离子间的静电引力等作用组装成三维的超分子.在2～300 K温度范围内测试了配合物的变温磁化率,结果表明,Ln(Ⅲ)-Fe(Ⅲ)之间存在反铁磁性相互作用.%Two isostructural heteronuclear complexes [Fe(phen)3]2[FeLn(H2O)(tiron)3] ·6H2O (Ln=Ho (1) and Yb (2)),Na2H2tiron=disodium 4,5-dihydro-xybenzene-1,3-disulfonate) were self-assembly synthesized via hydrothermal reaction.The complexes crystallized in the cubic system,space group P2,3.In [FeLn(H2O)(tiron)3]6-unit was revealed that the Fe3+ ion is in a FeO6 distorted trigonal anti-prism coordination polyhedron completed by six phenolate O atoms from three tiron4-ligands,and Ln3+ in a LnO7 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 coordinated water.The [Fe(phen)3]3+ cations and [FeCe(tiron)3]6-anions via πrπr interaction between phen ligands and electric attraction between cations and anions was assembled into multidimensional supramolecule.The magnetic properties of the complexes were been determined in the temperature range 2～300 K,indicating that the antiferromagnetic interaction between the central Ln(Ⅲ)-Fe(Ⅲ) ions.CCDC:866880,1; 867589,2.
