| Abstract: The complex of {[Zn(4,4′-bipy)(H2O)4]·(4,4′-bipy)·(2,6-NDS)·2H2O}n (2,6-NDS=2,6-naphthalenedisul-fonate; 4,4′-bipy=4,4′-bipyridine) has been synthesized by hydrothermal method and further characterized by X-ray single crystal structural analysis, fluorescence spectrum and thermogravimetric analysis. The complex crystallizes in triclinic system, space group P1, with a=0.777 760(10) nm, b=1.152 940(10) nm, c=1.908 48(2) nm, α=88.790 0(10)°, β=78.972 0(10)°, γ=89.588 0(10)°. The complex forms a 1D chain-like structure through bridging 4,4′-bipy ligands, in which Zn2+ ion is coordinated with two nitrogen atoms of two 4,4′-bipy molecules and four water oxygen atoms. The coordination environment of the Zn2+ ion can be described as a distorted octahedron. 2D (4,4) network structure is formed through hydrogen bonds between free 4,4′-bipy molecules and coordinated water molecules. Fluorescent spectrum of the complex exhibits emission peaks at 378 and 396 nm. CCDC: 722363. |
