By the self‐assembly of 2‐aminobenzimidazole ( L ), Nadca (Nadca = dicyanamide sodium) and CdCl 2 , a novel one‐dimensional (1D) Cd II coordination polymer [Cd( μ 1,5 ‐dca)( μ 1,3,5 ‐dca) L ] n ( 1 ) ( L = 2‐aminobenzimidazole) has been synthesized and structurally characterized by single crystal X‐ray diffraction, element analysis and FT‐IR spectra. In 1 μ 1,5 ‐bidentate and μ 1,3,5 ‐tridentate dca ligands bridge Cd II ions to form a 1D tube‐like structure, which presents a new 1D tubular structural motif of (3.4(2))(3(2).4(2).5(3)) topology in M‐dca systems (M = metallic). Solid‐state blue fluorescence spectrum of 1 also has been determined and compared with that of free ligand.
