文摘

A new 3D complex, {[Cd₃(HL)₂(H₂L)(H₂O)₄]路2H₂O}_n (1) (H₄L = 1,1鈥?(1,4-phenylenebis(methylene))bis(1H-imidazole-4,5-dicarboxylic acid), has been hydrothermally synthesized and characterized by elemental analyses, IR, TG, and X-ray single-crystal diffraction. Complex 1 is the first framework based on Cd^II ion and semi-rigid bis-IDC ligand. The (6,6)-net architecture of 1 is built from H₂L^{2 鈭?/sup> ligands linking 1D chain-like [Cd₃(HL)₂]_n SBUs, which formed by HL3 鈭?/sup> anions bridging two kinds of metal centers. In addition, complex 1 was demonstrated to display strong blue-violet fluorescence emission in the solid state at room temperature.}
