A proton-conductive complex {[Ni(H2O)8][H(H2O)2.5](HINO)4(PW12O40)}n,was constructed by a self-assembly of cations,[Ni(H2O)8]2+ cations,[PW12O40]3-anions and isonicotinic acid N-oxide (HINO).Single-crystal X-ray diffraction analysis at 293 K revealed that the title complex presented exactly a three-dimensional (3D) hydrogen-bonded network with large one-dimensional (1D) channels.Interestingly,[PW12O40]3-anions just filled in the 1D channels and self-assembled into poly-Keggin-anion chains.Thermogravimetric analysis shows no weight loss in the temperature range of 20~100 ℃,indicating that all water molecules in the unit structure are not easily lost below 100 ℃.The title complex was characterized by a satisfactory ionic conductivity (1×10-3~2×10-3 S·cm-1) in the temperature range 85 to 100 ℃.CCDC:825709.
