In an article, author is Jin, Guo-Xia, once mentioned the application of 877399-00-3, Name is (R)-5-Bromo-3-(1-(2,6-dichloro-3-fluorophenyl)ethoxy)pyridin-2-amine, molecular formula is C13H10BrCl2FN2O, molecular weight is 380.04, MDL number is MFCD18207061, category is pyridine-derivatives. Now introduce a scientific discovery about this category, Formula: C13H10BrCl2FN2O.
Three Ag-I, Cu-I and Cd-II coordination polymers based on the new asymmetrical ligand 2-{4-[(1H-imidazol-1-yl)methyl]phenyl}-5-(pyridin-4-yl)-1,3,4-oxadiazole: syntheses, characterization and emission properties
The new asymmetrical organic ligand 2-{4-[(1H-imidazol-1-yl)methyl]phenyl}-5(pyridin-4-yl)-1,3,4-oxadiazole (L, C17H13N5O), containing pyridine and imidazole terminal groups, as well as potential oxdiazole coordination sites, was designed and synthesized. The coordination chemistry of L with soft AgI, CuI and CdII metal ions was investigated and three new coordination polymers (CPs), namely, catena-poly[[silver(I)-mu-2-{4-[(1H-imidazol-1-yl)methyl]phenyl}5-(pyridin-4-yl)-1,3,4-oxadiazole] hexafluoridophosphate], {[Ag(L)]PF6}n, catena-poly[[ copper(I)-di-mu-iodido-copper(I)-bis(mu-2-{4-[(1H-imidazol-1-yl)methyl]phenyl}-5-(pyridin-4-yl)-1,3,4-oxadiazole)] 1,4-dioxane monosolvate], {[Cu2I2(L)(2)]mu C4H8O2}n, and catena-poly[[[dinitratocopper(II)]-bis(mu-2-{4-[(1Himidazol-1-yl)methyl]phenyl}-5-(pyridin-4-yl)-1,3,4-oxadiazole)]-methanol-water (1/1/0.65)], {[Cd(L)(2)(NO3)(2)]mu 2CH4O mu 0.65H2O}(n), were obtained. The experimental results show that ligand L coordinates easily with linear AgI, tetrahedral CuI and octahedral CdII metal atoms to form one-dimensional polymeric structures. The intermediate oxadiazole ring does not participate in the coordination interactions with the metal ions. In all three CPs, weak pi-pi interactions between the nearly coplanar pyridine, oxadiazole and benzene rings play an important role in the packing of the polymeric chains.
