2-硝基-4-甲基苯胂酸分子中的胂酸基能与稀土元素络合显色,是合成重要显色剂的反应中间体。了解它的结构,对设计合成路线、研究反应机理以及探索稀土元素的分析方法有着十分重要的意义。本文报道2-硝基-4-甲基-苯胂酸多晶样品X射线衍射数据,利用改进的尝试法将所有衍射数据指标化。该方法亦适用于六方、四方、正交、单斜和三斜物质粉末衍射数据的指标化。
The 2-nitro-4-methylbenzenesulfonic acid molecules in arsenic acid complex with rare earth elements complex color, is the synthesis of an important reagent intermediates. Understanding its structure is very important for designing synthesis routes, studying reaction mechanism and exploring rare earth elements. In this paper, the X-ray diffraction data of 2-nitro-4-methyl-phenylarsonic acid polycrystalline samples were reported. All the diffraction data were normalized by the improved method. This method is also suitable for the indexing of powder diffraction data of hexagonal, tetragonal, orthoganal, monoclinic and triclinic materials.
