A 1D Double Chains Architecture Based on the Pyridine-2- Sulfonate, 4,4'-Bipyridine and Acetate-Bridged of Zn(II) Complex: Synthesis, Spectral, Thermal Properties, and Crystal Structure

摘要

A new 1D double chains Zn(II) supramolecule framework, {[Zn2(2-pSO3)2(Ac)2(4,4'-Bipy)2[(4,4'-Bipy)}_n (I) (2-pSO3H = pyridine-2-sulfonate, 4,4'-Bipy = 4,4'-bipyridine), was synthesized by reaction of Zn(CH3COO), · 2H2O in methanol-water mixed solution and characterized by X-ray diffraction, elemental analysis, and IR spectrum. X-ray analysis indicates that I is a coordination polymer in which two deprotonated 2-pSO3H through the aromatic nitrogens in trans positions, oxygens in cis positions and two N atoms of 4,4'-Bipy and two μ2-Ac~- ligands, resulting in a ZnN3O3 distorted octahedral geometry. The 1D coordination polymer was connected to 2D and 3D supramolecule framework via π-stacking and weak C-H···O contacts. The complex I also displays strong fluorescence property and good thermal stability.
