The new title one-dimensional Cd coordination polymer, [Cd(CHN)(μ-N)] , has been synthesized and structurally characterized by single-crystal X-ray diffraction. The asymmetric unit consists of a Cd ion, one azide and one 1-benzyl-imidazole (bzi) ligand. The Cd ion is located on an inversion centre and is surrounded in a distorted octa-hedral coordination sphere by six N atoms from four symmetry-related azide ligands and two symmetry-related bzi ligands. The Cd ions are linked by double azide bridging ligands within a μ-N end-to-end (EE) coordination mode, leading to a one-dimensional linear structure extending parallel to [100]. The supra-molecular framework is stabilized by the presence of weak C-H⋯N inter-actions, π-π stacking [centroid-to-centroid distance of 3.832 (2) Å] and C-H⋯π inter-actions between neighbouring chains.
新型一维镉配位聚合物[Cd(CHN)(μ-N)] 已通过单晶X射线衍射法合成并进行了结构表征。不对称单元由一个镉离子、一个叠氮化物和一个1-苄基咪唑（bzi）配体组成。镉离子位于一个对称中心上，被来自四个对称相关叠氮化物配体的六个氮原子和两个对称相关的bzi配体包围在一个扭曲的八面体配位球中。镉离子通过双叠氮桥连配体以μ-N端对端（EE）配位模式相连，形成一个平行于[100]延伸的一维线性结构。超分子框架通过相邻链之间存在的弱C-H⋯N相互作用、π-π堆积[质心到质心距离为3.832 (2) Å]和C-H⋯π相互作用得以稳定。
