摘要A new complex, [Cd(L)2(pbda)]n (1) (L = 3-(2-pyridyl)-4-(p-methoxyphenyl)-5-(2-thienyl)- 1,2,4-triazole, H2pbda = 1,4-benzenedicarboxylic acid), has been hydrothermally prepared and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis and PXRD. The complex crystallizes in monoclinic, space group P21/c with a = 8.2929(9), b = 21.668(2), c = 10.9940(11) Å, β = 90.242(2)º, V = 1975.5(4) Å3, Z = 2, C44H32N8O6S2Cd, Mr = 945.30, Dc = 1.589 g/cm3, μ = 0.721 mm-1, S = 1.097, F(000) = 960, the final R = 0.0590 and wR = 0.1045 for 3846 observed reflections (I > 2σ(I)). In the title complex, the rigid bridging pbda2- ligands utilize oxygen atoms of carboxylate groups to coordinate with Cd(II) atoms to form one-dimensional chains which are further interlinked into a three-dimension framework via the intermolecular weak interactions. Photoluminescence study revealed that complex 1 exhibits strong fluorescent emission band in the solid state at room temperature.
