摘      要：A novel metal-organic framework, namely [Zn（C20H13OsP）]n （1）, has been hydro- thermally synthesized through the reaction of 5-（oxidediphenylphosphino）isophthalic acid （H2L） with Zn（II） salt. The title compound crystallizes in monoclinic, space group P21/c with a = 11.0966（10）, b = 14.5651（14）, c = 14.7311（15） A, fl = 130.022（6）°, C2oH13OsPZn, Mr = 429.64, V= 1823.3（3） ./k3, Dc = 1.565 g/cm3, F（000） = 872, g = 1.463 mm＂1, S = 1.054 and Z = 4. The final R = 0.0270 and wR = 0.0739 for 2769 observed reflections with 1 〉 20（/）. In the title complex, the Zn2（CO2）2 binuclear clusters are linked by L2- ligands to result in a pillared layer structure in the bc plane, which is a （4,4）-net composed of helical chains with opposite chirality by sharing Zn2（CO2）2 units. Adjacent＇layers are further associated together through Zn-O bonds involving the metal center and the oxygen atom of P=O group to achieve a 3D architecture, in which one-dimensional qua＆angled channel displays the interweaving of two pairs of coaxial double-helical chains with opposite chirality. The luminescence property and thermogravimetric analysis of the title complex were investigated.
