摘要
采用普通溶液法合成了配合物[Zn(eiqnthz)_2]·DMF(1)和[Zn3(piqnthz)_2Cl_2]·2H_2O(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。
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?髤ion.CCDC:1543732,1;1577230,2.
