摘      要：Using 4-aminopyridine as the structure-directing agent（SDA）, a new open-framework zinc phosphite, （CsH7N2）2·[Zna（HPO3）4]（ZnHPO-CJ70）, was synthesized under hydrothermal condition. Single-crystal X-ray diffraction analysis reveals that ZnHPO-CJ70 is constructed by the strictly alternating ZnO4 tetrahedra and HPO3 pseudo-pyramids, with their vertexes linked to generate a three-dimensional（3D） open framework with intersecting 8- and 12-ring channels. Further characterizations of ZnHPO-CJ70 were performed by means of X-ray powder diffraction（XRD）, elemental analysis（ICP, CHN）, infrared spectroscopy（IR） and thermogravimetric（TG） analyses. The results of luminescent test shows that ZnI-IPO-CJ70 exhibits strong fluorescence emissions in the solid state at room temperature.
