| 摘要: 利用3-吲哚乙酸(IAA)、邻菲啰啉(o-phen)和氯化锌在水-乙醇体系合成了一种金属配合物[Zn(IAA)2(o-phen)] (1)，并对其进行了X-射线单晶衍射分析、热重分析、元素分析、红外光谱、紫外光谱、荧光光谱表征。结构分析表明，该配合物中，锌离子处于四配位的四面体构型中，分别与2个IAA阴离子的羧基氧原子及1个邻菲啰啉的2个氮原子配位。通过超分子作用力：氢键和面对面式的π…π堆积作用力的自组装作用使这些分子形成二维的超分子层结构，继而这些层层间通过边对面式的π…π堆积作用力进一步的组装成三维的超分子结构。热重分析显示，该配合物具有较高的热稳定性。配合物的液态及固体荧光性质研究表明，此配合物具有一定荧光性质。 | |

| Abstract: A Zn(Ⅱ) complex, [Zn(IAA)2(o-phen)] (1) (IAA=3-indoleacetic acid, o-phen=1,10-phenanthroline), was synthesized and characterized by single crystal X-ray diffraction, TGA analysis, elemental analysis, IR, UV-vis and luminescence spectroscopy. For complex 1, each ZnⅡ ion is in the tetra-coordinated tetrahedral geometry from two mono-dentated IAA anions and one chelated o-phen ligand. The H-bonds and the face-to-face π…π stacking interactions assemble 2D supramolecular layer-structure, then via the edge-to-face C-H…π stacking interactions the 2D layers are constructed into 3D supramolecular structure. The TG analysis shows the complex possesses a high thermal stability. The solution and solid-state photoluminescence of 1 are presented. CCDC: 819169. | |
