pH controlled supramolecular structures of new silver(I) complexes based on 2-sulfoterephthalic acid and 4,4′-bipyridine
چکیده انگلیسی


• Four new silver(I) supramolecular polymers were synthesized.
• Their structures have been determined by single crystal X-ray diffraction analyses.
• The structures of coordination polymers 1–4 are all 3D supramolecular structures.
• The pH of reactions plays an important role in the assembly of the polymers.
• The photoluminescent properties of the coordination polymers were investigated.

Four new silver(I) supramolecular polymers, namely {[Ag2(2-Hstp)(bipy)]·H2O}n (1), {[Ag2(bipy)2]·(2-H2stp)·2H2O}n (2), {[Ag(2-stp)(bipy)][Ag(bipy)][Ag(bipy)]·6H2O}n (3) and {[Ag(2-stp)(bipy)][Ag(bipy)][Ag(bipy)]·10H2O}n (4) (2-NaH2stp = 2-sulfoterephthalic acid monosodium salt, bipy = 4,4′-bipyridine) were constructed from 2-sulfoterephthalic acid and 4,4′-bipyridine ligands. These compounds were also characterized by elemental analysis, Fourier transform infrared (FT-IR) spectra, and single-crystal X-ray diffraction studies. In 1, two neighboring silver ions are bridged by nitrogen and oxygen in a syn-upright bridging mode, forming a 2D Ag network. The molecular structure of 2, 3 and 4 are cation–anion species, forming 3D supramolecular structures formed by hydrogen-bonding interactions.
