A new bitrack sinusoid-like chain templated by Wells-Dawson type polyoxometalate was written by Wang, Xiuli;Hu, Hailiang;Tian, Aixiang;Lin, Hongyan;Li, Jin;Shi, Limin. And the article was included in Inorganic Chemistry Communications in 2010.Name: 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole This article mentions the following:
A new Wells-Dawson type polyoxometalate (POM)-templated compound, [Cu4(娓?sub>2-O)2(4,4′-bpo)4(INA)2(H2O)4][(P2W18O62)]璺疕2O (I, 4,4′-bpo = 2,5-bis(4-pyridyl)-1,3,4-oxadiazole; INA = pyridine-4-carboxylic acid), has been hydrothermally synthesized. I contains a novel bitrack sinusoid-like chain constructed from alternating dicopper units and non-linear rigid 4,4′-bpo linkers. Induced by POM templates, the adjacent chains formed elliptical spaces to accommodate the Wells-Dawson type anions. In the experiment, the researchers used many compounds, for example, 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7Name: 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole).
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 锜?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 锜?bonds. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.Name: 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole
