| 摘要: 配体3，4-吡啶二酸(H2pdc)和CaCO3反应合成了配合物[Ca2(pdc)2(H2O)7] (1)，用单晶X-射线、FTIR和元素分析对生成的晶体进行了表征。Ca(Ⅱ)采取八配位扭曲四方反棱柱几何构型，整个pdc2-作为三齿桥联配体连结3个不同的Ca(Ⅱ)原子形成一维链结构，一维链由π-π相互作用和O-H…N氢键连结形成二维层，二维层再进一步由O-H…O氢键连结形成三维结构。还研究了配合物1的荧光和热重性质。CCDC：806131。 |

| Abstract: The title complex [Ca2(pdc)2(H2O)7] (1), where H2pdc is 3,4-pyridinedicarboxylic acid, was obtained by using H2pdc and CaCO3 under evaporation process. Its structure was determined by single-crystal X-ray diffraction analyses and further characterized by IR spectrum and elemental analyses. Complex 1 is one-dimensional chain structure, in which the Ca(Ⅱ) takes eight-coordinated distorted square antiprism geometry. Each pdc2- anion acts as a μ3-bridge to form one-dimensional structure. The two-dimensional layers are constructed through π-π interactions and O-H…N hydrogen bond. The three-dimensional structure is formed by O-H…O hydrogen bonding interactions. Luminescent property and thermogravimetry analyses of complex 1 were investigated. CCDC: 806131. |
