苯甲酰羟胺(C_6H_5CONHOH)对钨钼配位效率高,速度快,生成的配合物稳定.在一定的酸性条件下,对钨钼萃取具有较好的分离性能.等及 Agrawal 曾报道该类钨钼配合物均易被高级醇定量萃取,可用于分光光度法测定微量钨和钼.但对配位过程的研究,特别是对配合物结构与性能的研究则未见报道.本文在钨配合物组成、红外光谱、多晶 X 光衍射等研究的基础上培养其单晶,并测定了晶体结构,试图对其性能研究提供一些信息.实验与结构分析配合物(C_7H_6O_2N)_2WO_2由钨酸钠与苯甲酰羟胺混合的水溶液,在 pH-1～6时,用己醇
Benzoyl hydroxylamine (C_6H_5CONHOH) has the advantages of high coordination efficiency to tungsten and molybdenum, high speed and stable complex. Under certain acidic conditions, it has better separation performance for tungsten and molybdenum extraction. Molybdenum complexes are easily quantitatively extracted by higher alcohols and can be used for the determination of trace amounts of tungsten and molybdenum by spectrophotometry.But the study on the coordination process, especially the study on the structure and properties of complexes has not been reported.In this paper, (C_7H_6O_2N) _2WO_2 was prepared by the single crystal and the crystal structure was determined based on the study of its composition, infrared spectrum and polycrystal X-ray diffraction.The experimental and structural analysis of the complex (C_7H_6O_2N) _2WO_2 by sodium tungstate and Benzoyl hydroxylamine mixed aqueous solution, at pH-1 ~ 6 with hexanol
