| 摘要: 通过水热法得到了2个配位聚合物{[Cd(L)(oba)]·3.5H2O}n(1)和{[Cd(L)2](p-bdc)}n(2)(L=4，4’-二(1-咪唑基)苯砜，H2oba=4，4’-联苯醚二甲酸，p-H2bdc=对苯二甲酸)，对它们进行了元素分析、红外光谱分析，并利用X射线衍射测定了它们的单晶结构。晶体结构分析表明，配合物1具有四连接二重穿插的三维网络结构，其拓扑为{65·8}。配合物2具有四连接的二维结构，其拓扑为{44·62}。此外，在室温下对2个配合物进行了荧光分析。 |

| Abstract: Two coordination polymers, namely {[Cd(L)(oba)]·3.5H2O}n (1) and {[Cd(L)2](p-bdc)}n (2) have been obtained by the reaction of cadmium nitrate, 4,4'-bis(imidazol-l-yl)-phenyl sulphone (L) with two aromatic carboxylic acids, 4,4'-oxydibenzoic acid (H2oba), terephthalic acid (p-H2bdc). They were characterized by IR, elemental analysis and X-ray diffraction. Compound 1 exhibits 4-connected 2-fold interpenetrating 3D networks with the point symbol of {65·8}. Compound 2 can be characterized as a 4-connected sql tetragonal planar network with the point symbol of {44·62}. The luminescent properties of two compounds have also been investigated. |
