| 摘要: 在室温和甲醇/水溶液为溶剂的条件下,以四溴代对苯二甲酸(H2TBTA)及1,3-二(4-吡啶基)丙烷(BPP)为配体合成了[Zn(TBTA)(BPP)]n (1)和[Cd(TBTA)(BPP)2(H2O)2]n (2)2个配位聚合物,对其进行了X-射线单晶衍射、元素分析、红外光谱分析和热重等性质表征。结果表明:配合物1为二维(2D)层状网络结构;配合物2为一维(1D)链状结构;H2TBTA配体中的羧基都采取单齿模式与金属离子配位;配合物中的氢键作用对其结构的稳定性起关键作用。 |

| Abstract: The complexes of [Zn(TBTA)(BPP)]n (1) and [Cd(TBTA)(BPP)2(H2O)2]n (2) based on 2,3,5,6-tetrabromo-terephthalic acid (H2TBTA) and 1,3-bis(4-pyridyl)propane (BPP) have been constructed in CH3OH/H2O solution at room temperature. The structures and properties were characterized by the single-crystal X-ray diffraction, elemental analyses, IR spectra and thermogravimetric analyses. The results indicate the complex 1 is two dimension (2D) wave-like layer network, and the complex 2 is one dimension (1D) chain structure, and the carboxyl groups in H2TBTA ligands coordinate with metal ions in monodentate mode, and the H-bonding interactions contribute to the stabilities of the structures of the complexes.
