Coordination Frameworks based on 3,5-Bis(imidazole-1-yl)pyridine and Aromatic Dicarboxylate Ligands: Synthesis, Crystal Structures, and Photoluminescent Properties was written by Xu, Jiakun;Sun, Xiaochun;Yang, Lirong;Yan, Xincheng;Bi, Caifeng;Sun, Mi. And the article was included in Zeitschrift fuer Anorganische und Allgemeine Chemie in 2014.Name: 3,5-Di(1H-imidazol-1-yl)pyridine The following contents are mentioned in the article:
Three metal coordination polymers [Zn(bdc)(L)(H2O)]n (1), [Co(pta)(L)(H2O)2]n (2), and [Cd(tda)(L)(H2O)]n (3) [H2bdc = 1,2-benzene dicarboxylate acid, H2pta = terephthalic acid, H2tda = 2, 5-thiophenedicarboxylic acid, L = 3,5-bis(imidazole-1-yl)pyridine] were synthesized and structurally characterized by IR spectroscopy, elemental anal., x-ray powder diffraction, and X-ray single crystal diffraction. Complex 1 shows a three-dimensional (3D) structure with cco topol. with the symbol 65路8, whereas complex 2 features a 3-dimensional structure with cds topol. with the symbol 65路8. Complex 3 has a 2-dimensional network constructed by the cadmium atoms bridged through the ligands tda and L. Their x-ray powder diffraction patterns were compared with the simulated ones. Also, their luminescent properties were studied in the solid state at room temperature, and the thermogravimetric analyses were carried out to study the thermal stability of the 3-dimensional networks. This study involved multiple reactions and reactants, such as 3,5-Di(1H-imidazol-1-yl)pyridine (cas: 1374155-84-6Name: 3,5-Di(1H-imidazol-1-yl)pyridine).
3,5-Di(1H-imidazol-1-yl)pyridine (cas: 1374155-84-6) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Name: 3,5-Di(1H-imidazol-1-yl)pyridine
