The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 2-(Pyridin-4-yl)-1H-benzo[d]imidazole( cas:2208-59-5 ) is researched.Name: 2-(Pyridin-4-yl)-1H-benzo[d]imidazole.Liu, Ying-Ying; Wang, Zhao-Xi; He, Xiang; Shao, Min; Li, Ming-Xing published the article 《One unexpected mixed-valence Cu(I,II)-cyanide coordination polymer in situ originating from the cleavage of acetonitrile》 about this compound( cas:2208-59-5 ) in Inorganic Chemistry Communications. Keywords: copper pyridylbenzimidazole cyanide complex preparation mixed valence; thermal stability luminescence copper pyridylbenzimidazole cyanide; crystal structure copper pyridylbenzimidazole cyanide. Let’s learn more about this compound (cas:2208-59-5).
Solvothermal reaction of CuCl2·2H2O and 2-(4-pyridyl)benzimidazole (PyHBIm) in a acetonitrile-water mixed solvent afforded a mixture of [CuI2CuII(CN)2(PyHBIm)2Cl2]n (1) and [CuII(PyH2BIm)2Cl4] (2). Complex 1 is a mixed-valence 1D ribbon Cu(I,II)-cyanide coordination polymer. One Cu(II) center linearly links two Cu(I) ions via two μ2-CN bridges. XPS spectrum and bond valence sum (BVS) anal. have confirmed the mixed-valence characteristics. Cu(II) ion adopts a centrosym. square-planar geometry surrounded by two cyanides and two pyridyl groups. Cu(I) ions adopt a trigonal geometry coordinated by cyanide, imidazole group and Cl- anion. The cyanide ligand is in situ generated from the cleavage of acetonitrile solvent, which indicates that acetonitrile is an environmentally friend cyanating agent. The mechanism of acetonitrile in situ cleavage under solvothermal condition is explained. Complex 2 is a centrosym. mononuclear Cu(II) compound Four equivalent Cl- anions lie on the equatorial plane. The protonated PyH2BIm+ cation as a monodentate ligand coordinates to Cu(II) center via pyridyl terminal.
