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) ,β = 90.242(2)o,V = 1975.5(4) 3,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.
