文摘

The copper-iodine based coordination polymer [Cu₄I₂(bmte)]_n (1) [H₂bmte = 1,2-bis(5-methyl-1H-1,2,4-triazol-3-yl)ethane] was synthesized using cuprous iodide and a flexible 3-substituted, ethyl-bridging bis(triazole) ligand under solvothermal conditions. X-ray diffraction analysis reveals that compound 1 shows a 3D framework containing Cu₄I₄ clusters and alternating left- and right-handed [Cu(triazole)] helices, which result in a (4,8)-connected fluorite (flu) topological network. Moreover, compound 1 exhibits orange phosphorescence with the emission maxima at 590 nm in the solid state at room temperature.
