| Abstract: | Two new metal-organic materials, In(2,2′-bipy)(btec)0.5Cl (1) and In2(phen)4(Hbtec)2 (2) (btec = 1,2,4,5-benzenetetracarboxylate, 2,2′-bipy = 2,2′-bipyridyl, phen = 1,10-phenanthroline) have been synthesized under mild hydrothermal condition. Their structures were determined by single-crystal X-ray diffraction and further characterized by X-ray powder diffraction, thermogravimetric analysis, IR, fluorescence spectroscopy, inductively coupled plasma (ICP) and elemental analysis. The structural analysis reveals that compound 1 exhibits a novel wavelike 2D layer with unusual contorted rhombic grids, while compound 2 possesses dinuclear In2(phen)4(Hbtec)2 complex molecules. It is noteworthy that their structures finally extend to the higher dimensional supramolecular framework structures through the π-π stacking interactions of N-donor ligands. Additionally, these two compounds show strong fluorescence in the solid state at room temperature. |
