And the article was included in Journal of Coordination Chemistry in 2011.Computed Properties of C12H8N4O This article mentions the following:
Two new Co complexes based on benzene tricarboxylates 1,2,4-H3BTC (1,2,4-H3BTC = 1,2,4-benzenetricarboxylate) or 1,3,5-H3BTC (1,3,5-H3BTC = 1,3,5-benzenetricarboxylate), and the bent dipyridyl ligand 2,5-bis(3-pyridyl)-1,3,4-oxadiazole (3-bpo) or its 4-pyridyl N-donor analog 2,5-bis(4-pyridyl)-1,3,4-oxadiazole (4-bpo), formulated as [Co(1,3,5-BTC)(4-bpo)(H2O)3]2[Co(H2O)6]·10H2O (1) and [Co3(1,2,4-BTC)2(3-bpo)2(H2O)12] (2), were hydrothermally synthesized and characterized by elemental analyses, IR spectroscopy, TG analyses, and single-crystal x-ray diffraction. Structure anal. reveals that 1 is a 3-dimensional porous supramol. network based on the 1-dimensional polymer chain, in which discrete [Co(H2O)6]2+ units and lattice H2O mols. are dispersed. In 2, bridging 3-bpo and 1,2,4-BTC ligands connect cobalt ions to form a trinuclear Co unit. Adjacent trinuclear Co units are further linked by π-π stacking interactions and H-bonding interactions to form a 3-dimensional supramol. framework. Electrochem. properties of Co(II) compounds as bulk-modified carbon paste electrodes (1-CPE and 2-CPE) were studied. In the experiment, the researchers used many compounds, for example, 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7Computed Properties of C12H8N4O).
2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.Computed Properties of C12H8N4O
