本文以四氟对苯二甲酸(H2tfbdc)和2,2′-联吡啶(bpy)为配体,合成了2个锌(Ⅱ)的配合物[Zn2(bpy)4(Htfbdc)2(tfbdc)](1)and[Zn(bpy)(H2O)2(tfbdc)](2)。并用元素分析、红外光谱、X-射线单晶衍射结构分析、热重分析等对其进行了表征。化合物1和2均属于三斜晶系,空间群为P1。配合物1和2中的锌(Ⅱ)离子分别位于畸变的八面体和畸变的三角双锥构型中。配合物1为双核结构,它们通过分子间氢键进一步形成一个二维的结构;配合物2是一个单核的两性离子,两性离子间通过氢键形成一个三维的空间网状超分子结构。考察了两种配合物的固体荧光性质。
In this paper, two zinc (Ⅱ) complexes [Zn2 (bpy) 4 (Htfbdc) 2 (tfbdc)] have been synthesized using H2tfbdc and bpy as ligands. ] (1) and [Zn (bpy) (H2O) 2 (tfbdc)] (2). It was characterized by elemental analysis, infrared spectroscopy, X-ray single crystal diffraction structure analysis and thermogravimetric analysis. Compounds 1 and 2 all belong to triclinic system with space group P1. Zinc (Ⅱ) ions in complexes 1 and 2 are located in distorted octahedral and distorted triangular bipyramid configurations, respectively. Complex 1 is a dinuclear structure which further forms a two-dimensional structure by intermolecular hydrogen bonding. Complex 2 is a mononuclear zwitterion which forms a three-dimensional steric reticular supramolecular structure through hydrogen bonding. The solid fluorescence properties of the two complexes were investigated.
