A series of novel Cd(II) complexes based on α,β-unsubstituted dipyrrin ligands (dpm) has been prepared and characterised both in solution and in the solid state. These compounds are of the [Cd(dpm)(2)] type, with the coordination sphere of the metal centre occupied by two dpm chelates. Interestingly, in contrast to what has been reported for the Zn(II) analogues, in the presence of a pyridyl- or imidazolyl-appended dpm ligand, the coordination number of the Cd(II) cation can be increased to six, leading to an octahedral coordination sphere. As a consequence, the formation of 1-, 2-, and 3D coordination polymers by self-assembly is observed. Photophysical investigations of the discrete complexes and self-assembled networks have demonstrated that both types of compounds are luminescent in the solid state.
一系列基于α,β-未取代二吡咯配体（dpm）的新型 Cd(II) 配合物已被制备并在溶液中和固态下进行了表征。这些化合物为 [Cd(dpm)₂] 型，金属中心的配位球由两个 dpm 螯合物占据。有趣的是，与 Zn(II) 类似物的报道相反，在存在吡啶基或咪唑基 appended dpm 配体的情况下，Cd(II) 阳离子的配位数可以增加到六，从而形成八面体配位球。因此，通过自组装观察到 1D、2D 和 3D 配位聚合物的形成。离散配合物和自组装网络的光物理研究表明，这两种类型的化合物在固态下均具有发光性。
