Self-assembly of the angular dipyridyl-type ligand 2,5-bis(3-pyridyl)-1,3,4-oxadiazole (L1) with CuII(BF4)2 or CuI(ClO4) affords a bimetallic macrocyclic compound [Cu2(L1)2(H2O)6](BF4)4·(H2O)3·(MeOH)0.5 (1) (similar to its CuII(ClO4)2 complex) or a novel trigonal-prismatic cage-shape species [(H2O)⊂ Cu2(L1)3(MeCN)2](ClO4)2 (2), resp. However, substituting L1 with its analogous 2,5-bis(4-pyridyl)-1,3,4-oxadiazole (L2) to react with CuI(BF4) yields a 1-dimensional infinite chain array {[Cu(L2)2(MeCN)](BF4)·(H2O)1.5}n (3), being similar to its CuI(ClO4) compound These results unequivocally suggest that the nature of the metal center and ligand functionality play the key role in formation of the coordination supramol. frameworks of 1–3. In the experiment, the researchers used many compounds, for example, 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7Related Products of 15420-02-7).
2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Related Products of 15420-02-7
