A novel 1D linear Zn(II) coordination polymer {[Zn(BPDC)(H2O)3]·3H2O}n (BPDC2−: 2,2′-bipyridine-4,4′-dicarboxylate) was obtained by hydrothermal methods. In this complex, an unusual coordination mode, which BPDC2− ligand adopts two N atoms and only one O atom to bridge Zn(II) ions into a rigid liner chain, is observed. The 1D chain further assembles into a 3D supramolecular architecture through hydrogen bonds and π–π interactions among chains. In addition, the complex exhibits a strong fluorescence at 381nm in the solid state, indicating that it may be a candidate for near ultraviolet luminescent material. A novel 1D linear Zn(II) coordination polymer {[Zn(BPDC)(H2O)3]3H2O}n (BPDC2−: 2,2′-bipyridine-4,4′-dicarboxylate) was synthesized hydrothermally, in which BPDC2− adopts two N atoms and only one O atom to bridge Zn(II) ions into a rigid liner chain. The complex exhibits a strong fluorescence at 381nm in the solid state.
