摘要: 以磺胺嘧啶为配体,合成了两种新的Zn(Ⅱ)配合物[Zn(L)2(bpy)] (1) and {[Zn(L)2(bpp)]}n (2) (L=磺胺嘧啶,bpy=2,2’-吡啶,bpp=1,3-二(4-吡啶基)丙烷)。并对其进行了单晶X-射线衍射,粉末X-射线衍射,元素分析,热分析,红外光谱,紫外光谱和荧光光谱测定。单晶X-射线分析表明化合物1是单核结构,属三斜晶系,P1 空间群,Zn(Ⅱ)是四方锥配位结构。化合物2是一维结构,属单斜晶系,P21空间群,Zn(Ⅱ)是四面体配位结构。热分析表明化合物1和2都有很高的热稳定性。 |

Abstract: Two new Zn(Ⅱ) compounds, [Zn(L)2(bpy)] (1) and {[Zn(L)2(bpp)]}n (2) (L=sulfonamide pyrimidine, bpy=2,2'-bipyridine, bpp=1,3-bis(4-pyridyl)propane), have been synthesized and characterized by single crystal X-ray diffraction, powder X-ray diffraction (PXRD), thermal analysis, elemental analysis, IR, UV-Vis and fluorescence. Single crystal X-ray analysis reveals that complex 1 is a mononuclear structure and the Zn(Ⅱ) ion exhibits a tetragonal pyramidal coordination geometry. Complex 2 is a one-dimensional structure and the Zn(Ⅱ) ion is a tetrahedral coordination geometry. Thermal analyses show that complex 1 and 2 have high thermal stability.
