摘　　要：选用的方法为一步水热合成法,通过调节反应体系的pH,控制原料的起始物质的量比,最终合成出一例具有新颖结构的化合物[Co(bpy)_(3)]_(2)[As_(2)W_(18)O_(62)],(bpy=2,2’-bipyridine).选择X-射线单晶衍射、IR、元素分析等对所合成的化合物进行相应的结构表征.该化合物是由多酸阴离子[As_(2)W_(18)O_(62)]^(6-)(简称As_(2)W_(18))与游离的两个金属有机配合物{Co(bpy)_(3)}构筑而成.紫外光的照射下,对其进行了光催化降解性能研究.In this paper,a novel compound[Co(bpy)_(3)]_(2)[As_(2)W_(18)O_(62)],(bpy=2,2’-bipyridine)was synthesized by hydrothermal method with adjust the pH value and the ratio of raw materials.The synthesized compound was characterized by X-ray single crystal diffraction,elemental analysis,IR.The title compound is composed of[As_(2)W_(18)O_(62)]^(6-)(abbreviate toAs_(2)W_(18))and two free metal organic complexes{Co(bpy)_(3)}.The photocatalytic degradation activity of the compound was studied under UV irradiation.
