为了进一步研究有机-无机杂化晶体材料的中心金属离子的交换反应,以间二茂铁基苯甲酸的钠盐作为配体,与Zn(OAc)2和辅助配体对二(三氮唑甲基)苯(btx)在常温下反应,得到一个新的双核配合物{[Zn(η2-OOCH4C6Fc)(OOCH4C6Fc)(btx)]2-(CH3OH)(H2O)2}(1).通过配合物1与Pb(Ⅱ)离子的中心金属离子交换反应,得到了它的反应产品{[Zn0.83-Pb0.17(η2-OOCH4C6Fc)(OOCH4C6Fc)(btx)]2(H2O)1.5}(2),并对其进行了X射线单晶衍射、原子吸收以及金属元素分析(ICP)和X射线能谱分析(EDS)的测定.结果证明,配合物1到2是通过单晶到单晶的转换产生的,该结果为金属配合物在有效去除有毒金属离子的应用上提供了理论基础.并显示了二聚二茂铁基羧酸锌配合物能被用来作为一个有效的阳离子交换材料去除铅离子,同时为利用类似的金属羧酸配合物选择性地交换阳离子打下了基础.
In order to further study the exchange reaction of central metal ions in organic-inorganic hybrid crystal materials, the reaction of Zn (OAc) 2 and the ancillary ligands of bis (triazolezole (Btx)] 2- (CH 3 OH) (H 2 O) 2} (1) was synthesized by the reaction of the complex with btx at normal temperature to obtain a new dinuclear complex {[Zn (η 2 -OCH 4 C 6 F c) 1] and Pb (Ⅱ) ion were obtained. The reaction product {[Zn0.83-Pb0.17 (η2-OOCH4C6Fc) (OOCH4C6Fc) (btx)] 2 (H2O) 1.5} , And their single crystal X-ray diffraction, atomic absorption and metal elemental analysis (ICP) and energy dispersive X-ray spectrometry (EDS) were measured.The results show that the complexes 1 to 2 through single crystal to single crystal conversion This result provides a theoretical basis for the application of metal complexes in the effective removal of toxic metal ions and shows that zinc dimerized ferrocenyl zinc complexes can be used as an effective cation exchange material to remove lead Ions while laying the groundwork for the selective exchange of cations with similar metal carboxylic acid complexes.
