以3-甲氧基水杨醛与乙醇胺缩合得到席夫碱化合物hmmpH2(hmmpH2=2-[(2-羟乙基亚氨基)甲基]-6-甲氧基苯酚),以hmmpH2为配体合成了配合物[Fe2(hmmp)2(hmmpH)2].1.5CH3CN.0.5H2O(1)和[Co2Na(hmmp)2(N3)2(CH3O)(CH3OH)2] (2).以3,5-二溴水杨醛与乙醇胺缩合得到化合物hmdbrpH2(hmdbrpH2=2-[(2-羟乙基亚氨基)甲基]-4,6-二溴苯酚),以hmdbrpH2为配体合成了一个混价三核配合物[Mn(Ⅱ)Mn(ⅡⅢ)2(hmdbrp)2(O2CPh)4(C H3OH)2]· 2CH3CN· 2CH3OH (3)(HO2CPh为苯甲酸).对配合物分别进行了元素分析、X射线单晶衍射分析,还对1和3进行了磁性研究.单晶结构分析表明配合物1中2个六配位的Fe(Ⅲ)离子通过2个醇羟基氧原子相连形成二聚体结构,配合物2中Co(Ⅲ)也为六配位,通过2个甲醇中氧原子相连形成双核结构,配合物3为一混价三核锰结构,3个Mn离子呈线性排列.磁性测试表明配合物1中Fe(Ⅲ)离子之间存在反铁磁相互作用,配合物3的三核锰单元内Mn(Ⅲ)、Mn(Ⅲ)离子之间存在反铁磁相互作用.%The Schiff base hmmpH2 (hmmpH2=2-[(2-hydroxyethylimino)methyl]-6-methoxyphenol) was synthesized by o-vanillin and ethanolamine.Complexes [Fe2(hmmp)2(hmmpH)2]· 1.5CH3CN ·0.5H2O (1) and [Co2Na((hmmp)2(N3)2 (CH3O)(CH3OH)2] (2) were synthesized by using hmmpH2 ligand.The Schiff base hmdbrpH2 (hmdbrpH2=2-[(2-hydroxyethylimino)methyl]-4,6-dibromophenol) was synthesized by 3,5-dibromosalicylaldehyde and ethanolamine.Complex [Mn (Ⅱ) Mn(lⅢ) 2 (hmdbrp)2 (O2CPh)4(CH3OH)2] · 2CH3CN · 2CH3OH (3) was synthesized by using hmdbrpH2 ligand.These complexes were fully characterized by elemental analysis and X-ray single crystal diffraction,and complexes 1 and 3 were also studied by magnetic investigation.The structural analysis indicates that in complex 1 two six-coordinated Fe(lⅢ) ions are bridged by two alcoholic hydroxyl atoms to form a dimer structure.In complex 2,Co(Ⅲ) is six-coordinated with an octahedral coordination environment and the two Co(l Ⅲ) ions are bridged by two O atoms from CH30H constructing a binuclear complex.The complex 3 is a mixed valence trinuclear structure,with three Mn ions in linear array.Magnetic study indicates that the antiferromagnetic interaction exist between Fe(Ⅲ) ions in complex 1,and in complex 3 antiferromagnetic interactions exist between the Mn(lⅡ) and Mn(llⅢ) ions in the trinuclear manganese unit.CCDC:1534804,1;1534805,2;1534806,3.
