Abstract The 3D netlike coordination polymer of ZnⅡ with benzimidazole-5,6-dicarboxylic acid (H₃BIDC), [Zn(HBIDC)·H₂O]_n was synthesized by the hydrothermal method through self-assembling. The crystal structure of complex 1 was characterized by single-crystal X-ray diffraction, elemental analysis and IR spectra, and we also studied the fluorescence properties of complex 1 in DMSO and in the solid state with UV-Vis absorption spectra, fluorescence spectra and fluorescence lifetime. Complex 1 has blue luminescence in solutions of DMSO with emission band at 481 nm; and has blue luminescence in the solid state at room temperature with a strong emission band at 493 nm, and these all can be attributed to the π^*→π transition based on the benzimidazole-5,6-dicarboxy acid. The experimental results indicate that complex 1 displays higher fluorescence quantum efficiency and can be used as a potential blue luminescence material.
