A novel three-dimensional (3D) polymer [Cd-2(Hbiim)(4)](n) (H(2)biim = 2,2'-biimidazole) 1 was obtained through hydrothermal reaction and characterized by single crystal X-ray diffraction, and the fluorescent property was also determined. Compound 1 crystallizes in a monoclinic chiral space group P2(1) and contains two types of helical chains. Hbiim(-) partially deprotonated of H(2)biim exhibits two different coordination modes, which contributes greatly to the formation of the 3D chiral framework. Compound 1 exhibits blue fluorescence at 488 nm in the solid-state upon excitation at 430 nm.
