以3,3 ' -（蒽-9,10-二基）二丙烯酸酯和不同n给体为原料，在溶剂热条件下合成了[Cd2(ADDA)(bipy)(H2O)2]·2H2O (1), [Zn(ADDA)(bipy)0.5]·NMP·2H2O (2), [Co(ADDA)(bip)(H2O)2]·H2O (3) （bipy = 4,4 ' -联吡啶，bip = 1,4-二（1h -咪唑-1-基）苯，H2ADDA = 3,3 ' -（蒽-9,10-二基）二丙烯酸）三个新的混合配体配位网络，并通过单晶x射线衍射分析对其结构进行了表征。红外光谱（IR）、元素分析、粉末x射线衍射（PXRD）和热重分析（TGA）。拓扑分析表明，1具有罕见的8连通三维ilc网络，点符号为{4∧24.5.6∧3}；配合物2具有基于无限Zn - (CO2)链的三维开放骨架，点符号为{6∧2.8∧4}；复合体3是一个正常的二维3连通配位网络，具有hcb拓扑，点符号为{6∧3}。此外，还研究了配合物1和2的发光性质。结果表明，配合物2在室温下对甲醇悬浮液中的Fe3+具有快速和选择性的传感能力。
Three new mixed-ligand coordination networks, [Cd2(ADDA)(bipy)(H2O)2]·2H2O (1), [Zn(ADDA)(bipy)0.5]·NMP·2H2O (2), and [Co(ADDA)(bip)(H2O)2]·H2O (3) (bipy = 4,4′-bipyridine, bip = 1,4-di(1H-imidazol-1-yl)benzene, H2ADDA = 3,3′-(anthracene-9,10-diyl)diacrylic acid), have been synthesized based on 3,3′-(anthracene-9,10-diyl)diacrylate acid and different N-donor ligands under solvothermal conditions, and structurally characterized by single-crystal X-ray diffraction analyses, infrared spectroscopy (IR), elemental analyses, powder X-ray diffraction (PXRD) and thermogravimetric analyses (TGA). Topological analysis reveals that 1 features a rare 8-connected 3D ilc network with the point symbol of {4∧24.5.6∧3}; complex 2 possesses a 3D open framework based on the infinite Zn–(CO2) chain with the point symbol of {6∧2.8∧4}; while complex 3 shows a normal 2D 3-connected coordination network with hcb topology and the point symbol of {6∧3}. Besides, the luminescence properties of complexes 1 and 2 were also investigated. The results show that complex 2 bears rapid and selective sensing of Fe3+ in methanol suspension at room temperature.
