| 摘要: 通过水热法合成了两种新型配合物{[La(pydc)(OAc)(H2O)]·2H2O}n(1)和{[Tm2Cu(pydc)4(H2O)6]·2H2O}n(2)(H2pydc=2,5-吡啶二羧酸),并对其结构进行了表征。结构分析表明配合物1是由2,5-吡啶二羧酸和醋酸构筑的具有一维方形孔道的复杂三维结构。配合物2中2,5-pydc2-阴离子配体采取μ2-η1-η1-和μ4-桥连两种配位模式,呈现出三维的开放式架构。此外,还进一步对配合物1,2的热稳定性和配合物2的磁学性质进行了研究。 |

| Abstract: Two new complexes, namely {[La(pydc)(OAc)(H2O)]·2H2O}n(1) and {[Tm2Cu(pydc)4(H2O)6]·2H2O}n(2) (H2pydc=2,5-pyridinedicarboxylic acid), have been synthesized and structurally characterized. Structure analyses reveal that complex 1 has intricate 3D micropore framework with 1D square channels, which is constructed by 2,5-pyridinedicarboxylate and acetate ligands. Complex 2 shows a 3D open framework in which 2,5-pydc2- dianion ligand adopts μ2-η1-η1- and μ4-bridge coordination mode. In addition, thermal stability for 1 and 2 and temperature-dependent magnetic susceptibilities for 2 have been investigated in detail. CCDC: 884201, 1;884200, 2. |
