Synthesis, Crystal Structure, and Properties of a New Zinc(II) Coordination Polymer With Mixed 4,4′-biphenyldisulfonic Acid and N-Donor Ligands
收藏资源简介：
A new zinc(II) coordination polymer, namely [Zn(bipy)<sub>2</sub>(H<sub>2</sub>O)<sub>4</sub>]<i><sub>n</sub></i>·<i>n</i>(dsba) (1), has been synthesized by the mixed 4,4′-biphenyldisulfonic acid (H<sub>2</sub>dsba) and 4,4′-bipyridine (bipy) ligands with Zinc(II) salt under the common solution evaporation method. The results of the X-ray crystal diffraction analysis show that complex 1 belongs to the monoclinic system with <i>P2<sub>1</sub>/c</i> space group. The unit cell constants of complex 1 are <i>a</i> = 9.2579 Å, <i>b</i> = 12.2016 Å, <i>c</i> = 14.447 Å, α = γ = 90˚, β = 93.476˚. Complex 1 exhibits a three-dimensional supramolecular network based on the discrete structure by utilizing various H-bonded interactions. In addition, the properties of complex 1, such as the elemental analysis, FT-IR spectroscopy, X-ray powder diffraction, and fluorescence spectroscopy were also characterized and are discussed in detailed.
