| Abstract: | Hydrothermal reaction of Cd(NO3)2·4H2O with bbp and p‐PDOAH2 at 140 °C yielded a novel 1D cadmium(II) coordination polymer, Cd(bbp)(p‐PDOA)]n (bbp?2,6‐bis(benzimidazol‐2‐yl)pyridine, p‐PDOA?p‐phenylenedioxy‐ diacetate dianion), in which CdN3O4 pentagonal bipyramids were linked by p‐PDOA ligands in a bis‐bidentate mode to construct a zigzag chain with the adjacent Cd···Cd distance of 1.14(1) nm. There exists a 2D supramolecular network linked by π‐π stacking with a face‐to‐face distance of 0.35(1) nm between the 2,6‐bis(benzimidazol‐2‐yl) pyridine ligands and hydrogen‐bonding interactions (0.27(4) nm). A 3D supramolecular network was further constructed by these non‐covalent interactions between the zippers. The TG/DTG showed that its chain skeleton was thermally stable up to 389 °C and the blue fluorescent emission of the complex was determined at 428 nm in a solid state with its long decay lifetime of 7.24 ns. |
