摘    要:通过模板法合成出一个由1,3-丙二胺(以下简写为丙二胺)桥联的双核铁(III)配合物Fe2(salpn)3](H2salpn=N,N’-bis(salicylaldehyde)propylenediimine).结果表明,该晶体属于单斜晶系。P2(1)/c点群,a=10.995(3)A,b=19.811(6)A,c=23.072(7)A,β=103.367(4)°,V=4889(2)A’,Z=4.中心离子Fe(III)离子与Schiff碱上的三个氮原子、三个氧原子配位,采用了轻微扭曲八面体的配位构型,salpn配体采用螯合的模式,相邻的分子片段再由丙二胺连成双核结构.磁化学测试结果显示,通过丙二胺桥联的Fe(III)离子之间存在着非常弱的反铁磁耦合作用.

关 键 词:单晶结构  铁(III)  双核配合物  反铁磁性  丙二胺桥联

Abstract:A new bridged dinuctear complex formulated as Fe2 ( salpn ) 3 ] ( H2salpn = N, N' -bis ( salicylaldehyde) propylenediimine Schiff base) has been synthesized from the template synthesis by reaction of 1,3-propylenediamine with salicylaldehyde in the presence of the iron (III ) salt. The metal center adopts a slightly distorted octahedral geometry, and the salpn ligands act in both bridging and chelating modes to form a dinuclear complex with unanticipated six-membered chelate rings. There exist very weak antiferromagnetic couplings between the Fe (III) cations through propylenediamine bridge.
Keywords:X-ray single crystal  iron dinuclear complex  antiferromagnetic properties  propylenediamine-bridge
