Abstract: The bis-β-diketone molecule incorporating 1,3-propanedithioether bridge between the γ-carbons of respective β-diketone units of 1,3-bis(3-thio-2,4-pentanedionate)propane(L1) was designed and synthesized via the Williamson reaction. The structure of bis-β-diketone L1 was characterized by elemental analysis, 1H NMR, 13C NMR, MS, IR, UV and X-ray single crystal diffraction analysis. The analysis results show that ]the crystal of bis-β-diketone L1 belongs to monoclinic, space group C2/c with cell parameters a=1.40679(9) nm, b=0.76521(5) nm, c=1.43213(10) nm, α=γ=90°, β=94.552°, V=1.53681(18) nm3, Z=4, Dc=1.316 g/cm3, μ=0.353 mm-1, F(000)=648, and bis-β-diketone L1 exists in the enol form in both solid state and chloroform solution. The recognition and extraction properties of the target compound L1 with metal ions were investigated by the ultraviolet spectroscopy. The results show that bis-β-diketone L1 has a good selective recognition and extraction property for Ni(Ⅱ) ion.
