In ethanol, a mononuclear cobalt(Ⅲ) complex incorporating 2′-(2-Thienylidene)-2-Hydroxybenzoylhydra- zide has been synthesized and characterized by IR, UV-Vis, elemental analysis and X-ray crystal structure analysis. The crystal belongs to triclinic system, space group P1 with cell constant, a=1.230 69(10) nm, b=1.329 18(11) nm, c=1.330 56(11) nm, α=113.702(2)°, β=91.590(2)°, γ=100.846(2)°, V=1.944 4(3) nm3, Z=2, μ=0.662 mm-1, Dc=1.482 g·cm-3, F(000)=896, Rint=0.048 7. The crystal structure shows an anionic didentate ligand O and N donors in this work. The cobalt(Ⅲ) atom is hexacoordinated with oxygen atom from keto group and nitrogen atom from amide to form a cobalt atom for the core octahedral structure. CCDC: 748882.
Chiral imidazole ionic liquid Chloride-[1-Ethyl-3-((S)-1,2-propanediol)]is synthesized from imidazole and(S)-3-chlorine-1,2-propanediol by two steps.The ionic liquid is characterized by 1HNMR spectra.Besides,its electrical conductivity in the different solvents is studied.The result is that the ionic liquid can be dissolved in acetonitrile,acetone,ethanol,water,N,N-dimethylformamide(DMF),but cannot be dissolved in ethyl acetate.The electric conductivity of the ionic liquid is also measured at different temperatures and concentrations,the result shows that the electric conductivity value increases along with the concentration and temperature rising,and the value of electric conductivity K is different in different solvents.Its order is :K(acetonitrile)≈ K(water)>K(DMF)>K(acetone)>K(anhydrous ethanol).
