Abstract: | A novel double‐helical‐chain coordination polymer Zn(nbdoa)(2,2′‐bipy)(H2O)]n constructed by flexible 2‐nitro‐benzene‐1,4‐di(oxyacetate) ligand and rigid 2,2′‐bipyridine ligand was obtained by hydrothermal reaction. The crystal structure demonstrates that there is a double‐helical chain with an inner channel running parallel to the helix axis without any interpenetration, which is connected to network via π‐π stacking and hydrogen bond interactions. The thermal analysis shows that the infinite helical structure is stable up to 536 K. The luminescence property is investigated and the complex shows photoluminescence in the solid state at room temperature. |
