摘要
The solvothermal reaction between cuprous iodide and the rigid triangular imidazole ligand in mixed N,N'-dimethylacetamide (DMA)-acetonitrile solvent leads to the isolation of the 3D metal-organic framework [(Cu4I4)(3)(TIPA)(4)]center dot 7DMA (1) [TIPA = tri(4-imidazolylphenyl) amine], which was characterized by elemental analysis, IR spectroscopy, powder X-ray diffraction, and single-crystal X-ray diffraction. Topologically, the structure of 1 is an unprecedented 3,3,4,4-connected net with a point symbol of {4.8.10}(2){4.8(2)}(2){4(2).8(2).10(2)}(2){8(4).12(2)}. Compound 1 exhibits orange-red photoluminescence with an emission maximum at 622 nm at room temperature.
