Two 3D Supramolecular Architectures from Ag(I) Coordination Polymers Constructed by Flexible Bis(benzimidazolyl)butane Ligand
Journal of Inorganic and Organometallic Polymers and Materials(2013)
摘要
Two Ag(I) coordination polymers, {[Ag(bib) 0.5 ]Cl·4H 2 O} n ( 1 ) with a 1D zigzag chain structure extended into a 3D supramolecular network by face-to-face π – π stacking interactions, and [Ag(bib)(Hpydca)] n ( 2 ) with the first example of three-connected uninodal fourfold interpenetrating ths network via hydrogen-bonding interactions (bib = 1,4-bis(benzimidazole)butane, pydca = pyridine-2,6-dicarboxylate) were synthesized under hydrothermal conditions and characterized by elemental analysis, IR, thermogravimetric analysis and single crystal X-ray diffraction. In addition, the fluorescence properties of 1 and 2 in the solid state were investigated at room temperature.
