二维无机-有机化合物的晶体结构及紫外研究

Crystal structure and UV-vis diffuse reflectance investigation of 2D compound

通过水热方法合成了二维无机-有机杂化化合物Co3(fcz)4(V3O9)2.2H2O.单晶X射线衍射分析表明化合物结晶于三斜晶系,P-1空间群.(V3O9)3-多阴离子连接Co(1)离子形成了金属氧链,该链进一步通过连接Co(2)离子形成二维无机层.fcz分子以双单齿的配位方式配位到同一个二维层的2个金属离子上,使化合物最终展示了二维结构.此外,还研究了该化合物固体的紫外-可见漫反射光谱.

The 2D inorganic-organic hybrid compound Co3（fcz）4（V3O9）2·2H2O has been isolated by hydrothermal method.X-ray single crystal diffraction analysis reveals that the compound crystallizes in triclinic and space group of P-1.In the structure,（V3O9）3-polyanions link Co1 ions to form a chain,which are linked by Co（2）ions to give a 2D inorganic layer.Fcz ligands coordinate to two Co2＋ ions from the same layer,and the compound shows a 2D net.In addition,we also investigated the UV-vis diffuse reflectance of the compound.
