| 摘 要： | 通过水热合成法合成了一个无机钒氧酸盐配合物Zn3V2O8(H2O)41,并应用红外(IR)、热重(TG)、X射线单晶衍射等对配合物的结构及性质进行了表征.由结构分析可知,它是由简单的{VO4}3-构筑的,配合物中含有有趣的Zn-O-Zn螺旋链.左螺旋与右螺旋Zn-O-Zn链由{VO4}3-交替连接形成一个二维层,六配位的Zn中心同样通过连接邻层中{VO4}3-而使结构扩展成三维结构.

| Abstract: | One new inorganic vanadium polyoxometalate complex, Zn3VzO8 （H20）4 1, have been synthesized under hydrothermal conditions and characterized by IR spectroscopy, TG, and singlecrystal X-ray diffraction. Structural analysis reveals that it is derived from the simple VO4 units, but it contains interesting helical Zn-O-Zn chains. Left and right Zn-O-Zn helical chains are linked into a two-dimensional layer through { VO4 }^3- units, six-coordinated Zn centers link the { VO4 }^3- units of the adjacent layers into a three-dimensional structure. |
