•One new CdII complex was constructed from the designed semi-rigid bis-IDC ligand.•The H4L ligands displayed two different coordination modes in complex 1.•The 3D framework of 1 was built by H2L2 − anions linking chain-like SBUs.•Both HL ligand and complex displayed good solid state luminescent properties.
A new 3D complex, {[Cd3(HL)2(H2L)(H2O)4]·2H2O}n (1) (H4L = 1,1′-(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 CdII ion and semi-rigid bis-IDC ligand. The (6,6)-net architecture of 1 is built from H2L2 − ligands linking 1D chain-like [Cd3(HL)2]n SBUs, which formed by HL3 − 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.
Graphical abstractA new complex based on the designed H3IDC derivative ligand with two IDC groups has been successfully synthesized under hydrothermal condition. Complex 1 exhibits a 3D 6-connected framework constructed from H2L2 – ligands linking chain-like SBUs formed by HL3− ligands bridging two different metal nodes. Moreover, the thermostability and luminescent properties complex 1 have been investigated.Figure optionsDownload full-size imageDownload as PowerPoint slide
