Crystal data for the title complex are as follows： monoclinic system, space group P21/n with a = 11.8015（7）, b = 15.9551（10）, c = 11.8858（8）A^°, β = 94.844（6）°, V = 2230.0（2） A^°3, Mr = 559.25, Z = 4, F（000） = 1124, Dc = 1.666 g/cm^3, μ（MoKα） = 1.106 mm^-1, R = 0.0269 and wR = 0.0569 for 4534 observed reflections with I 〉 2σ（I）. Complex 1 displays a 3D supermolecular structure based on the 1D zizag chains. Fluorescence spectrum measurement indicates that complex 1 shows strong fluorescence emission with a maximum peak at 447 nm in the solid state at room temperature.展开更多

Crystal data for the title complex are as follows: orthorhombic system, space group Ccmb with a = 11.5245(3) b = 19.5069(5) c = 11.4231(3) A, V = 2568.00(12) A3, Mr = 188.31, Z = 16, F(000) = 1480, Dc = 1.948 g/cm3, μ(Mo Kα) = 1.725 mm-1, R = 0.0195 and w R = 0.0462 for 1357 observed reflections with I 】 2σ(I). In the title complex, the central Cd(II) ion is located in a distorted octahedral coordination environment. Two Cd(II) ions are bridged by two pda2- ligands and one pyz ligand to form a bi-loop structure. Luminescent property of the complex has also been studied.展开更多
