Hydrothermal Synthesis and Characterization of a Novel 1D Luminescent Zn(II) Framework With 1,4-di-(1,2,4-triazole-4-yl) Benzene

Using the benzene-based bis-triazole ligand 1,4-di-(1,2,4-triazole-4-yl)benzene(L) and corresponding zinc(II) salt, under hydrothermal conditions, a novel luminescent 1D Zn(II) coordination polymer, {[Zn((2)-L)(H2O)(4)]SiF6 center dot 2H(2)O}(n) (1) has been isolated and characterized by single-crystal X-ray diffraction, FT-IR, and luminescent analysis. The crystal crystallizes in the Monoclinic C2/c space group, a = 12.997(5) angstrom, b = 19.376(4) angstrom, c = 8.080(6) angstrom, = 109.379(18)degrees, Z = 4. These L ligands adopt the bi-dentate bridging coordination modes to link neighboring Zn(II) ions forming 1D chain structure. Solid state luminescent spectrum of 1 also has been investigated indicating the strong emission band centered at 370nm. The result also represents a good example of the construction of these highly dimensional luminescent inorganic-organic hybrid frameworks.
