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

A new 1D double chains Zn(II) supramolecule framework, {[Zn-2(2-pSO(3))(2)(Ac)(2)(4,4'-Bipy)(2)](4,4'-Bipy)} (n) (I) (2-pSO(3)H = pyridine-2-sulfonate, 4,4'-Bipy = 4,4'-bipyridine), was synthesized by reaction of Zn(CH3COO)(2) center dot 2H(2)O 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-pSO(3)H through the aromatic nitrogens in trans positions, oxygens in cis positions and two N atoms of 4,4'-Bipy and two mu(2)-Ac- ligands, resulting in a ZnN3O3 distorted octahedral geometry. The 1D coordination polymer was connected to 2D and 3D supramolecule framework via pi-stacking and weak C-HaEuro broken vertical bar O contacts. The complex I also displays strong fluorescence property and good thermal stability.
