[M(L)2(NCS)2(H2O)2] (M = MnII or CoII and L = 2,5-bis(4-pyridyl)-1,3,4-oxadiazole): three-dimensional extended networks built from hydrogen bonds and π-π stacking interaction-syntheses and crystal structures was written by Fang, Ya-Yin;Liu, He;Du, Miao;Guo, Ya-Mei;Bu, Xian-He.

Two three-dimensional (3D) supramol. compounds [M(L)2(NCS)2(H2O)2] (M = Mn or Co; L = 2,5-bis(4-pyridyl)-1,3,4-oxadiazole) were synthesized and structurally determined by x-ray diffraction analyses. The crystal structures of both complexes reveal that they are isomorphic neutral mols. and the metal ions are at the center of symmetry. Each metal center is six-coordinated and the MN4O2 coordination sphere can be considered as an octahedron. The most striking feature of both complexes resides in the formation of a 3-dimensional network through the mutual effect of H bonds and π-π stacking. In the experiment, the researchers used many compounds, for example, 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7SDS of cas: 15420-02-7).
2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of â?8.7 à 10â? cm3·molâ?.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ·molâ? in the liquid phase and 140.4 kJ·molâ? in the gas phase. Pyridine derivatives are also useful as small-molecule α-helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.SDS of cas: 15420-02-7
