One new chiral metal-organic coordination polymer,[Cd_2(dpb)(H_2hfipbb)_2]_n,was obtained under hydrothermal conditions of 1,3-di(pyridineyl)benzene(dpb) and 4,4’-(hexafluoroisopropylidene)bis(benzoic acid)(H_2hfipbb). The title compound reveals a three-dimensional(3D) framework with two types of helical chains [Cd(COO)]n,which are linked each other to further form a double helical chain [Cd_2(COO)_2]_n by sharing the same Cd(Ⅱ) ions. The dpb connects the double helical chains to generate a 3D framework. These unique structures were studied by single-crystal X-ray and other spectroscopy techniques. In addition,the luminescent,fluorescence lifetime and second harmonic generation efficiency properties in the solid state have been studied.
