将Fe3+ 与 2 ,3—二氯异丁酸基的二元配合物分别与 2 ,2′—联吡啶、邻菲啉在无水乙醇中反应数小时 ,除去杂质 ,得到相应的 2种三元配合物 ,其元素分析结果得知二者的分子式分别为[Fe(C4 H5Cl2 O2 ) 3(C10 H8N2 ) ]和 [Fe(C4 H5Cl2 O2 ) 3(C12 H8N2 ) ]·H2 O ,通过红外光谱、紫外光谱、热重分析等物理化学方法进一步证实了它们的组成 ,并推断出二者中Fe3+ 的配位数为 6 ,其中 2个异丁酸基以单齿配位 ,2 ,2′—联吡啶或者邻菲啉是以 2个N原子配位成键 ,特别的是第 3个异丁酸基除了氧原子参加配位外 ,相邻的一个氯原子也参与了配位
The binary complexes of Fe3 + and 2,3-dichloroisobutyrate were respectively reacted with 2,2’-bipyridine and phenanthroline in absolute ethanol for several hours to remove impurities to obtain the corresponding two kinds of three tris Elemental analysis showed that the formulas of the two were [Fe (C4 H5Cl2 O2) 3 (C10 H8N2)] and [Fe (C4 H5Cl2 O2) 3 (C12 H8N2)] H2 O, respectively. , UV-Vis, TG-MS and other physical and chemical methods to further confirm their composition, and infer the two Fe3 + coordination number of 6, two of the isobutyric acid group monodentate coordination, 2, 2’- Bipyridyl or phenanthroline coordinates with two N atoms to form a bond. In particular, the third isobutyric acid group participates in coordination with an oxygen atom. One adjacent chlorine atom is also involved in coordination
