The synthesis and crystal structure of the three-dimensional coordination polymer of an angular dipyridyl ligand 2,5-bis(4-pyridyl)-1,3,4-oxadiazole (L) and Cu(ClO4)2, exhibiting the 1st CuII diamondoid network with 2-fold interpenetration, {[Cu(L)2(H2O)2](ClO4)(OH)(H2O)2.5}n (1), together with the Cu(OAc)2 complex of L, [Cu(L)2(OAc)2(H2O)](H2O)2(MeOH) (2), with an unexpected mononuclear structure, are reported. Crystal data for 1: tetragonal, space group I41/a, a = b 13.477(3), c 46.167(13) Å, Z = 8. Crystal data for 2: triclinic, space group P1̅, a 7.847(2), b 13.189(4), c 15.948(5) Å, α 75.225(7), β 79.945(6), γ 77.540(5)°, Z = 2. The magnetic properties and anion effect are also discussed. In the experiment, the researchers used many compounds, for example, 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7Application In Synthesis of 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. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Application In Synthesis of 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole
