Synthesis, Crystal Structure of 1‐D Double‐helical Chain Manganese(II) Coordination Polymer Constructed by 2,2′‐bpy and Flexible Dicarboxylate Ligand with Strong Fluorescent Emission

Abstract

AbstractA new coordination polymer [Mn2(nbdoa)2(2,2′‐bpy)2]n was obtained by hydrothermal reaction, which was constructed by 2,2′‐bpy and flexible ligand 2‐nitro‐benzene‐1,4‐di(oxyacetate). The crystal structure reveals that there exists 1‐D double‐helical chain, which is connected to 2‐D network via π‐π stacking interactions. The thermal analysis shows that the complex begins to decompose at 567 K. The luminescence property was investigated and the complex shows photoluminescence in the solid state at room temperature.
