Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2-(Pyridin-4-yl)-1H-benzo[d]imidazole, is researched, Molecular C12H9N3, CAS is 2208-59-5, about Solvothermal Synthesis and Diverse Coordinate Structures of a Series of Luminescent Copper(I) Thiocyanate Coordination Polymers Based on N-Heterocyclic Ligands.Category: indole-building-block.
Solvothermal reactions of CuSCN with 4-amino-3,5-bis(3-pyridyl)-1,2,4-triazole (3-Abpt), 5-(4-pyridyl)tetrazole (4-Ptz), and 2-(n-pyridyl)benzimidazole (n-PyHBIm, n = 4, 3, 2) in MeCN afford six novel coordination polymers: [Cu5(SCN)5(3-Abpt)2]n (1), [Cu(SCN)(3-Abpt)]n (2), [Cu(SCN)(4-Ptz)]n (3), [Cu2(SCN)2(4-PyHBIm)]n (4), [Cu2(SCN)2(3-PyHBIm)]n (5), and [Cu2(SCN)2(2-PyBIm)(2-PyHBIm)]n (6). All these complexes were structurally characterized by x-ray diffraction anal. 1 Is the 1st example of a 1,1,1,3-μ4-tetradentate thiocyanate complex which displays a three-dimensional (3D) polymeric framework constructed from thiocyanate and tetradentate 3-Abpt. 2 Exhibits a two-dimensional (2D) 4.82 network constructed from unidentate thiocyanate and tridentate 3-Abpt. 3 Is a 1-dimensional (1D) ladder-like double-chain polymer assembled by bidentate thiocyanate and 4-Ptz ligands. 4 Shows a 2-dimensional 1,1,3-μ3-thiocyanate Cu 4.82 network where bidentate 4-PyHBIm locates at both sides of the 2-dimensional layer. 5 Displays a 2-dimensional 63 network constructing from 1,1,3-μ3-thiocyanate and bidentate 3-PyHBIm. 6 Is a 1-dimensional 21 helical chain polymer constructing from 1,3-μ2-thiocyanate and 2-PyBIm anion. Bond valence sum (BVS) anal. and magnetic susceptibility indicate that 6 is a mixed-valence compound The coordinate diversity of thiocyanate is discussed. 1-6 Are all thermally stable up to 230-290°. They exhibit yellow or blue luminescence originating from ligand-to-metal charge transfer or ligand-centered emission.
