2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. 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.Synthetic Route of C12H8N4O

Hydrothermal synthesis, characterization and crystal structure of a three-dimensional (3D) ZnII supramolecular compound with ethylenediaminetetraacetic acid ligand and 4-(carboxylate)pyridinium guests was written by Du, Miao;Guo, Jian-Hua;Zhao, Xiao-Jun. And the article was included in Journal of Molecular Structure in 2004.Synthetic Route of C12H8N4O This article mentions the following:

A new supramol. compound [Zn(H2EDTA)(H2O)](Q)2(H2O)2 (1), where H4EDTA = EDTA and Q = 4-(carboxylate)pyridinium, was prepared by mild hydrothermal reaction and characterized by elemental anal., IR spectrum and TGA. Single-crystal x-ray diffraction of 1 [monoclinic, space group C2/c, a 11.310(4), b 9.704(4), c 23.798(10) Å, β 97.401(10)°, Z = 4] revealed that the ZnII ion coordinates to the chelating tetradentate ligand H2EDTA and a H2O mol., taking a distorted trigonal-bipyramid geometry. The mononuclear [Zn(H2EDTA)(H2O)] subunits are linked to form two-dimensional layered architectures by the lattice H2O moieties through O-H···O H bonds, which are further extended to a three-dimensional (3D) supramol. network by 4-(carboxylate)pyridinium guests (resulting from the ring-opening hydrolysis of 2,5-bis(4-pyridyl)-1,3,4-oxadiazole) through extensive H-bonding interactions. The 3-dimensional supramol. framework is also stabilized by significant face-to-face π-π stacking interactions between the aromatic pyridinium systems. In the experiment, the researchers used many compounds, for example, 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7Synthetic Route of C12H8N4O).
