Abstract Two new coordination polymers (CPs), [Zn(npba)2] (1) and [Cd(npba)2] (2), have been hydrothermally synthesized from Zn(NO3)2·6H2O/Cd(NO3)2·6H2O and 3-nitro-5-(pyridin-3-yl) benzoic acid (Hnpba). The products have been characterized by IR spectroscopy, elemental analysis, thermogravimetric analysis, and single-crystal X-ray diffraction. In CP 1, the four-coordinated Zn(II) centers are bridged by npba ligands to generate chains, which are connected through arene π–π stacking interactions to generate a layer structure. In CP 2, the six-coordinated Cd(II) centers are also bridged by npba ligands to form chains with similar connectivity. The photoluminescence properties of CPs 1 and 2 were studied.

两种基于 3-nitro-5-(pyridin-3-yl)benzoic acid 的发光 d10 金属配位聚合物

摘要 以 Zn(NO3)2·6H2O/Cd(NO3)2·水热法合成了两种新型配位聚合物 (CPs)，[Zn(npba)2] (1) 和 [Cd(npba)2] (2)。 6H2O 和 3-nitro-5-(pyridin-3-yl) 苯甲酸 (Hnpba)。产品已通过红外光谱、元素分析、热重分析和单晶X射线衍射表征。在 CP 1 中，四配位的 Zn(II) 中心通过 npba 配体桥接生成链，链通过芳烃 π-π 堆积相互作用连接以生成层状结构。在 CP 2 中，六配位的 Cd(II) 中心也由 npba 配体桥接形成具有相似连接性的链。研究了CP 1和2的光致发光特性。
