由H+(H2O)2.5阳离子,[Ni(H2O)8]2+阳离子,[PW12O40]3-阴离子和异烟酸氮氧化物(HINO)自组装成一个具有质子导电性的化合物{[Ni(H2O)8][H(H2O)2.5](HINO)4(PW12O40)}n。293 K的单晶X-射线衍射分析表明标题化合物形成1个带有一维通道的三维氢键网络结构。[PW12O40]3-阴离子填充在一维通道内并且自组装成多阴离子链。热重分析表明在20~100℃范围内化合物没有失重,表明化合物结构单元内所有的水分子在100℃以下不易失去。标题化合物在85~100℃范围内表现出好的离子导电性(1×10-3~2×10-3S.cm-1)。
Self-assembly of a compound {[Ni (H 2 O) 2] with proton-conducting compounds by H + (H2O) 2.5 cation, [Ni (H2O) 8] 2+ cation, [PW12O40] 3- anion and isonicotinic acid oxynitride (HINO) ) 8] [H (H2O) 2.5] (HINO) 4 (PW12O40)} n. Single crystal X-ray diffraction analysis of 293 K showed that the title compound formed a three-dimensional hydrogen-bonded network with one-dimensional channels. [PW12O40] 3- Anions are packed in one-dimensional channels and self-assemble into polyanion chains. Thermogravimetric analysis shows that the compound has no weight loss in the range of 20-100 ° C, indicating that all the water molecules in the structural unit of the compound are not easily lost below 100 ° C. The title compound showed good ionic conductivity (1 × 10 -3 to 2 × 10 -3 S · cm -1) at 85 to 100 ° C.
