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.Recommanded Product: 2-(Pyridin-4-yl)-1H-benzo[d]imidazole.Yang, Yan; Zeng, Ming-Hua; Zhang, Lai-Jun; Liang, Hong published the article 《A zinc(II) coordination polymer, [Zn4(o-bda)4(p-pbim)4]n, with strong blue fluorescence》 about this compound( cas:2208-59-5 ) in Journal of Coordination Chemistry. Keywords: zinc pyridylbenzimidazole phenylenediacetato polymeric complex preparation structure; crystal structure zinc pyridylbenzimidazole phenylenediacetato polymeric complex; fluorescence zinc pyridylbenzimidazole phenylenediacetato polymeric complex. Let’s learn more about this compound (cas:2208-59-5).
A zinc(II) coordination polymer, [Zn4(o-bda)4(p-pbim)4]n (1) (p-pbim = 4-pyridylbenzimidazole, o-bda2- = o-phenylenediacetic acid dianion), has been synthesized by hydrothermal method and characterized by elemental anal., IR, TG, photoluminescence and X-ray single crystal diffraction. Complex 1 crystallizes in a monoclinic system and space group P21/n, with a = 14.231(3) Å, b = 16.257(4) Å, c = 16.794(4) Å, β = 100.262(1)°, and Z = 8; R1 for 6475 observed reflections [I > 2σ(I)] was 0.0420. Complex 1 shows a bi-chain structure fabricated by the tetranuclear zinc unit. Two zinc(II) ions are five coordinate with distorted trigonal-bipyramid geometry and the other two zinc(II) ions are four coordinate with distorted tetrahedral geometry. Complex 1 builds the 1-D bi-chain structure with two different sub-rings A and B, which are 32-member and 14-member rings, resp. There exists a 2-D supramol. network linked by hydrogen-bonding interactions (2.695 and 2.807 Å). A 3-D supramol. network is further constructed by non-covalent interactions between the 1-D bi-chain structure. The TG/DTG shows that the chain skeleton is thermally stable to 356°C. Blue fluorescent emission of the complex was determined at 404 nm in the solid state with short decay lifetime of 1.67 ns.
