摘要: 采用普通溶液法合成了配合物[Zn(eiqnthz)2]·DMF(1)和[Zn3(piqnthz)2Cl2]·2H2O(2)(Heiqnthz=N,N'-乙酰异喹啉甲酰肼,H2piqnthz=N,N'-丙酰异喹啉甲酰肼)。通过X射线单晶衍射分析、X射线粉末衍射分析、红外光谱分析、热重分析以及荧光光谱分析等分析方法对2个配合物进行结构测定和性质表征。结构分析表明配合物1是单核结构,单斜晶系,空间群为C2/c,锌离子周围有4个氮原子和2个氧原子与之配位,形成一个畸变的N4O2八面体构型。配合物2属于单斜晶系,C2/c空间群,三核结构。中心原子Zn(1)、Zn(2)、Zn(3)均为5配位,Zn(1)、Zn(3)位于分子两端并且是变形四角锥配位构型,Zn(2)位于中间形成三角双锥配位构型,整体呈V字型。荧光分析表明Heiqnthz、H2piqnthz与锌(Ⅱ)离子配位后其荧光都发生较大的红移。

Abstract: Two new metal-organic complex,[Zn(eiqnthz)2]·DMF (1) and[Zn3(piqnthz)2Cl2]·2H2O (2) (Heiqnthz=N,N'-acetyl isoquinoline hydrazine, H2Piqnthz=N,N'-propionyl isoquinoline hydrazine), has been synthesized by common solution method. The structures and properties of complexes 1 and 2 are determined and characterized by single-crystal X-ray analysis, XRD powder diffraction analysis, infrared spectroscopy, thermal stability analysis and fluorescence analysis method. The crystal structural analysis revealed that the complex 1 crystalizes in monoclinic, space group C2/c, with 4 nitrogen atoms and 2 oxygen atoms from two ligands to forming a N4O2 distorted octahedral coordination geometry around the zinc ions. The complex 2 belongs to monoclinic system, space group C2/c as a three nuclear structure. Zn(1), Zn(2), Zn(3) ions are penta-coordinated, and the whole molecule presents V shape. Zn(1) and Zn(3) are located at both ends of the molecule and deformed tetragonal pyramidal coordination structures. Zn(2) is located in the middle to form a triangular bipyramid coordination structure. The fluorescence spectroscopic analysis demonstrated that Heiqnthz and H2piqnthz have red-shifted phenomenon after coordinated with zinc(Ⅱ) ion.
