| 摘要: 以醋酸锌、5-溴-1，2，4-苯基三羧酸(BTCAH3)和4，4’-联吡啶(4，4’-bipy)为原料，在水热条件下合成了1个三维框架结构化合物[Zn3(BTCA)2(4，4’-bipy)2](1)，利用红外光谱、元素分析、热重、X-粉末衍射以及X-单晶衍射对该化合物进行了表征。化合物1是单斜晶系，C2/c空间群。在化合物1中，锌离子通过BTCA3-配体的羧酸氧原子形成一个具有3-节点、4-连接的三维框架结构。4，4’-联吡啶配体在框架结构中连接锌离子。另外，研究了该化合物的热稳定性和固体荧光性质。 |

| Abstract: A novel coordination polymer, [Zn3(BTCA)2(4,4'-bipy)2](1) (BTCAH3=5-bromobenzene-1,2,4-tricarboxylic acid, 4,4'-bipy=4,4'-bipyridine) has been synthesized utilizing Zn(OAc)2·2H2O, the rigid 5-bromobenzene-1,2,4-tricarboxylic acid and 4,4'-bipy under the hydrothermal reaction. Compound 1 was characterized by infrared spectroscopy, elemental analysis, thermogravimetric analysis and single crystal X-ray diffraction analysis. In 1, the Zn(Ⅱ) ions are linked through the carboxylate oxygen atoms of the BTCA3- anions, forming a three-dimensional framework structure with 3-nodal and 4-connected net with Schläfli symbol of (4·7·84)2(4·74·8)2(74·82). The 4,4'-bipy ligand coordinates the Zn(Ⅱ) ions in the framework. In addition, the thermal stability and luminescent properties of Compound 1 were also investigated in this paper. CCDC: 811925. |
