摘要
0引言
基于二茂铁及其衍生物独特的结构特征、灵活多样的配位模式,以及该类化合物在非线性光学材料、分子磁体材料、液晶材料以及均相催化等领域的重要用途而倍受关注。人们尝试通过把二茂铁引入到其他的分子体系中得到一些新型的含二茂铁基的化合物,其中二茂铁羧酸衍生物作为一类性能优良的配体已被广泛应用于构筑功能配合物,并且已有较多的二茂铁单甲酸、二茂铁双甲酸的配合物被报道。
A new 1D chain coordination polymer [Pb(η^2-FcL)2(phen)]n is obtained by slow evaporation of the solution, and characterized by the elemental analyses, 1↑H NMR, IR and thermogravimetric analysis. The crystal structure has been analyzed by X-ray diffraction. The title complex belongs to triclinic system with space group P1. Each Pb(Ⅱ) ion is coordinated by O atoms from carboxylic of p-ferrocenylbenzoate in μ3-bridge mode and the N atoms from phenanthroline in chelated mode. The Pb(Ⅱ) ions are connected by bridging O atoms leading to the infinite 1D chain. In addition, the π-π stacking interaction between the phenanthroline molecules can increase the stability of the complex. The thermogravimetry analysis indicates that the this complex is stable before 255.9 ℃.
