Two new coordination polymers that contain di-Cu (Cu2) units were prepared using Cu(OAc)2·H2O in combination with (1,3,4)-oxadiazole organic ligands L1 and L2 with dipyridyl substituents in MeOH. The compounds were characterized by single crystal x-ray diffraction, IR spectroscopy, and TGA. The structure of compound 1 (monoclinic, space group C2/c, a 19.9952(14), b 7.5005(5), c 16.0442(11) Å, β 109.000(10)°, Z = 4) features 1-dimensional zigzag chains that are cross-linked into a novel three-dimensional network by weak noncovalvent π-π interactions between the 3-pyridyl rings on the L1 ligand. Compound 2 (monoclinic, space group C2/c, a 27.428(2), b 13.3833(11), c 8.6339(7) Å, β 103.973(2)°, Z = 4) also features a zigzag chain motif. In the solid state, small and large hexagonal channels are found in 1 and 2, resp. Compounds 1 and 2 are new examples of metal dimer-containing coordination polymers. 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. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Related Products of 15420-02-7
