本文研究了两种二茂铁硫杂冠醚配体(Ⅰ:1-二茂铁2,14-二硫-14-冠-5;Ⅱ:1-二茂铁2,8,14-三硫-14-冠-5;)对Hg~(2+)、Co~(2+)、Pb~(2+)、Cu~(2+)、Zn~(2+)的配合性能。结果表明,配体Ⅱ的配合能力高于配体Ⅰ,但Ⅰ和Ⅱ的配合能力都遵从Hg~(2+)>Cu~(2+)>Zn~(2+)>Pb~(2+)>Cd~(2+)的顺序。此外,还制备了配体Ⅰ与Cu~(2+)、Ag~+、Au~(3+)、Zn~(2+)、Cd~(2+)、Hg~(2+)的固体配合物,并根据元素分析、红外光潜和差热-热重分析结果确定了各配合物的组成。
In this paper, two kinds of ferrocenylthiocarbacyclic ether ligands (Ⅰ: 1-ferrocene 2,14-dithio-14-crown-5; Ⅱ: 1-ferrocene 2,8,14- -14-crown-5;) on the Hg ~ (2 +), Co ~ (2 +), Pb ~ (2+), Cu ~ (2 +), Zn ~ (2+) The results showed that the complexation ability of ligand Ⅱ was higher than that of ligand Ⅰ, but the complexing ability of Ⅰ and Ⅱ followed Hg 2+> Cu 2+ + Zn 2+ + Pb 2+ + )> Cd ~ (2+) order. In addition, a solid complex of ligand Ⅰ with Cu 2+, Ag 2+, Au 3+, Zn 2+, Cd 2+ and Hg 2+ The composition of each complex was determined according to elemental analysis, infrared photo-latent heat and thermogravimetric analysis.
