摘要
本文以乙酰丙酮和1,4-二(邻氨基苯氧基)丁烷进行缩合得到Schiff碱配体L,再分别同CoCl2.6H2O和ZnCl2.4H2O进行配位反应,得到了2个配合物[CoLCl2]n(1)和[ZnLCl2]n(2),并用元素分析,FTIR和X-射线单晶衍射进行了表征。结果表明,配合物1和2属于异质同晶,均属于正交晶系,空间群均是Pna21。在化合物1和2中,每个Co(Ⅱ)和Zn(Ⅱ)的配位环境均为扭曲四面体,2个配合物中每个配体L通过其两臂乙酰丙酮亚胺单元的端基氧原子同2个金属离子配位桥联形成一维链结构。
The Schiff base ligand L was synthesized from condensation reaction of 1,4-（o-aminophenoxy）butane with acetyacetone.CoCl2·6H2O and ZnCl2·4H2O each react with L to give two complexes [CoLCl2]n（1） and [ZnLCl2]n（2）,and characterized by elemental analysis,FTIR and single crystal X-ray diffraction.The results of structural analysis indicate that both complexes are isostructural and belong to the orthorhombic Pna21 space group,the coordination environment of Co（Ⅱ）and Zn（Ⅱ）are a distorted tetrahedron.In the two complexes,each L ligand links two metal atoms using two terminal oxygen atom from acacH-imine units belonging to two L ligands to generate a one-dimensional（1D） chain structure.
