摘要:
通过水热法成功合成了两个过渡金属锗磷酸盐化合物Cs[MⅡGe(OH)2(H0.5PO4)2](MⅡ=Co,Fe),并采用粉末X射线衍射、单晶X射线衍射、红外光谱分析和热分析方法对样品进行表征.结果表明:这两个过渡金属锗磷酸盐化合物同构,是为数不多的具有二维层状结构的锗磷酸盐; 同时由于Ge元素的d轨道电子数排满,姜-泰勒效应不明显,使得化合物Cs[MⅡGe(OH)2(H0.5PO4)2](MⅡ=Co,Fe)结构中由GeO4(OH)2八面体和MⅡO4(OH)2(MⅡ=Co,Fe)八面体通过共棱连接的一维金属链相对较直.
Abstract:
In this paper,the synthetic chemistry of transition metal germanophosphates system has been explored.Two isostructural transition metal germanophosphate compounds Cs[MⅡGe(OH)2(H0.5PO4)2](MⅡ=Co,Fe)were successfully synthesized by hydrothermal method.And the compounds were characterized using powder X-ray diffraction,single crystal X-ray diffraction,infrared spectroscopy and thermal analysis methods.Their crystal structures,determined from single crystal data,possessed two-dimensional layered structures built from single chains of edge-sharing MⅡO4(OH)2 and GeO4(OH)2 octahedra,and the single chains were interconnected by HPO4tetrahedra.At the same time,the single chain of edge-sharing MⅡO4(OH)2 and GeO4(OH)2 octahedra was relatively straight compared with other metal phosphates,this may attribute to the weak John-Teller effect of germanium element,for which the d-orbital was full filled with electrons.
