| 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。 |

| Abstract: 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.
