Synthesis, Crystal and Hirshfeld Surface Structure of a 1D Ni(II) Coordination Polymer: Luminescent Detection for Fe3+ in H2O. Issue 17 (30th April 2021) - Ya‐Li,
Abstract: A one‐dimensional (1D) Ni(II) coordination polymer, {[Ni(oba)(1, 3‐bix)(H2 O)]⋅H2 O} n (1 ), where H2 oba=4, 4′‐oxybis(benzoic acid) and 1, 3‐bis(imidazol‐l‐yl‐methyl)benzene=1, 3‐bix, was hydrothermally synthesized and characterized through IR spectroscopy, elemental and thermal analysis, single‐crystal X‐ray diffraction, and Hirshfeld surface analyses. X‐ray diffraction structural analysis has revealed that the oba and 1, 3‐bix ligands connects the Ni(II) atoms to form a square‐wave 1D chain, which is further extended into 2D supramolecular layers through O−H⋅⋅⋅O hydrogen bonds and π⋅⋅⋅π stacking interactions. 1 shows intense luminescence in H2 O and exhibits a selectivity and detection for Fe 3+ ions through the fluorescence quenching effect at room temperature. Abstract : A one‐dimensional double chains Ni(II) coordination polymer ({[Ni(oba)(1, 3‐bix)(H2 O)]⋅H2 O} n, 1 ) derived of oba 2− and 1, 4‐bix ligands has been hydrothermally synthesized and fully structural characterized. The fluorescence measurements show 1 can act as a fluorescent sensor for Fe 3+ in H2 O and the detection limit is reached to 1.30 mM.
