以Dawson型多金属氧酸盐和异烟酸为原料,合成了一种新的超分子化合物(C6NO2H6)6[α-P2W18O62].10H2O.通过元素分析、红外光谱、热重分析和X射线单晶衍射确定了该化合物的组成和结构.结构解析表明:该化合物是通过[α-P2W18O62]6-多氧阴离子和质子化的异烟酸阳离子之间的静电引力与广泛的氢键相互作用形成3D超分子结构.同时也进行了电化学及紫外光谱研究.
A novel supramolecular compound (C6NO2H6) 6 [α-P2W18O62] .10H2O was synthesized from Dawson-type polyoxometallates and isonicotinic acid. Elemental analysis, IR, TG and XRD The crystal composition and structure of the compound were confirmed by X-ray diffraction, and the structure analysis showed that the compound was formed by the electrostatic attraction between [α-P2W18O62] 6-polyoxoanion and protonated isonicotinic acid cation with extensive hydrogen bonding interaction 3D supramolecular structure. At the same time also conducted electrochemical and UV spectroscopy.
