| 摘要: 在溶剂热条件下，合成了2个基于V型辅助配体（bipmo、bppmo）的镉配位聚合物{[Cd （bipmo）（NDC）]·1.75H2O}n（1）和{[Cd （bppmo）（NDC）（H2O）]·H2O}n（2），其中H2NDC=2，6-萘二羧酸，bipmo=双（4-（1H-咪唑-1-基）苯基）甲酮，bppmo=双（4-（吡啶-4-基）苯基）甲酮。利用单晶X射线衍射、键价和分析、红外光谱和元素分析对其结构进行了表征。研究发现，配合物1具有二重互穿的{63}拓扑结构。配合物2同样是3-连接的{63}拓扑，却存在三重穿插结构。分析表明，V型配体对最终结构的形成有很大影响。此外，对配合物1和2的发光性质也进行了详细研究。 |

| Abstract: Based on V-shaped auxiliary ligands, two novel coordination polymers, {[Cd(bipmo)(NDC)]·1.75H2O}n (1), {[Cd(bppmo)(NDC)(H2O)]·H2O}n (2), where H2NDC=2,6-naphthalenedicarboxylic acid, bipmo=bis(4-(1H-imidazol-1-yl)phenyl)methanone, bppmo=bis(4-(pyridin-4-yl)phenyl)methanone, have been synthesized under solvothermal conditions. They have been characterized by single-crystal X-ray diffraction, bond valence sum calculations, IR spectra, and elemental analyses. Complex 1 shows 2-fold interpenetrating sheets of {63} topology, which interpenetrate in a 2D → 2D parallel manner. Complex 2 reveals a 3-fold interpenetrating {63} network. The results indicate that the V-shaped ligands have a great effect on the formation of the final structures. In addition, the luminescent properties of complexes 1 and 2 were investigated in detail. |
