【摘要】 A novel Cd(Ⅱ) coordination polymer with diacylhydrazide ligand N,N?-bis(3-methoxysalicyl)-2,6-pyridinedicarbohydrazide(H6msphz),[Cd2(H2msphz)(Py)4]n(1,Py = pyridine) has been synthesized through solvothermal reaction and structurally characterized by single-crystal X-ray diffraction,IR,TGA and PXRD investigations. It crystallizes in triclinic system,space group P1,with a = 11.0230(11),b = 11.7264(15),c = 17.3395(14) ?,α = 70.520(9),β = 84.806(7),γ = 81.965(9)°,V = 2089.9(4) ?3,Dc = 1.638 gcm–3,μ = 1.083 mm-1,F(000) = 1032,Z = 2 and S = 1.040. In complex 1,the H2msphz4-ligand uses not only its coordinated pocket to catch one Cd(Ⅱ) ion,but also its two terminal groups to chelate other two Cd(Ⅱ) ions,leading to the formation of a chain structure. The adjacent chains are further assembled together by two kinds of π-π interactions between the Py rings,resulting in the finial double layered supramolecular structure. In addition,complex 1 is found to show photoluminescence in the solid state at room temperature,which can be ascribed to the intraligand π→π* transitions.
