| 摘 要： | 采用水热合成法合成了一种结构新颖的多硼钒氧簇化合物Mn2[V12B16O52(OH)6](en)2(H3O)6(H2O)5(en=ethylenediamine)1,通过单晶X射线衍射确定该化合物的结构。化合物1中,在ab平面上,簇单元之间通过[Mn(H2O)2]2+连接成二维层状结构,另外,层与层之间在c方向上通过氢键连接成三维空间结构。此外,对化合物1的谱学性质进行了红外光谱、磁和热微扰下的二维红外相关光谱、紫外-可见固体漫反射光谱分析,探讨了其结构与谱学性质的关系。磁微扰的二维红外相关光谱表明B—O,V—O—V和Mn—O—B的伸缩振动对于磁场的变化比较敏感,热微扰的二维红外相关光谱表明B—OH,B—O,V—O—V和Mn—O—B的伸缩振动对热微扰比较敏感。

| Abstract: | A novel polyoxovanadium borate Mn2[V12B16O52(OH)6](en)2(H3O)6(H2O)5 1(en=ethylenediamine) was hydrothermally synthesized and characterized by IR,two-dimensional infrared(2D IR) correlation spectroscopy with magnetic and thermal perturbation,and single crystal X-ray diffraction.In 1,it is interesting that each [V12B16O52(OH)6]14-units is connected by four [Mn(H2O)2]2+ to generate a 2D layer on the ab plane.Along c axis,these layers are further linked by H-bond to form a 3D framework.The response of the stret... |
