摘要: A series of tetranuclear Cu4I4(Ln)2 clusters (1−3) supported by the chelating 4,4′-(4,5-diX-1,2-phenylene)bis(1-benzyl-1H-1,2,3-triazole) ligands (L1, X = H; L2, CH3; L3, F) have been prepared. Crystal structure determinations shown that adopt a distorted “step-type” geometry in which triazole exhibit both and bridging coordination modes to Cu(I) ions. When L3 was employed 3:2 CuI/L3 ratio, crystalline product, 4, obtained. Product 4 is actually 1:1 cocrystallization cluster 3 (denoted 4a) dinuclear Cu2I2(L3)2 complex (4b). X-ray structures 1, 2, show presence close Cu···Cu contacts forms. 1H NMR experiments indicate rapid exchange occurs these systems. All are brightly luminescent solid state at 77 K room temperature with λmax 495−524 nm. Emission intensity decays fit single exponential lifetimes on order 10 35 microse...
