摘　　要：在酸性条件下,一个新的拥有一维锯齿链超分子的二维化合物[CoO6V10O28]Cl4.17H2O被合成。并用元素分析,IR光谱,TG分析和X-射线单晶衍射进行表征,晶体的结构是空间立体的。其空间结构是:a=9.0511;b=11.328;c=11.749;β=97.60,V=1118.9 3,Z=2。同时X-射线单晶衍射分析结果显示,标题化合物是由一个[V10O28]6-阴离子,6个氧原子配位的钴原子,4个氯原子和17个结晶水构成。另外,分子的配位水之间存在氢键作用。结果标题化合物结构拓展成为二维结构。A new two- dimensional supramolecular framework with one- dimensional （1 - D） zigzag chains, [CoO6V（10）O（28）]Cl4·17H2O was synthesized under acidic condition and characterized by elemental analysis, 1R spectrum, therrnogravimetric （TG） analysis and single - crystal X - ray diffraction.The crystal crystallizes in monoclinic, space group of P21/c with a=9.0511A;b=11.328A;c=11.749A;β=97.60,V=1118.9A^ 3,Z=2. In the structure of 1. The X - Ray diffraction analysis result showed that, the title compound is by[V10O28 ]^6- anion,6 oxygen atoms coordinate cobalt atom,4 chlorine atoms and 17 crystal water constitutions.. Moreover, There exist the hydrogen bonds function between the molecular coordinate water, Finally the title compound structure was extended into the two- dimensional structure.
