components in the two complexes, metal ions, ferrocenyl‐substituted carboxylate units and 2,2′‐bipy. Such complexes containing ferrocenyl‐substituted carboxylate and bipyridine‐based ligands are rare. The solution‐state differential pulse voltammetries of the complexes were determined. The results indicate that the half‐wave potential of the ferrocenyl moiety is influenced by the Zn(II) ion.
处理两种二茂铁基取代的羧酸盐配体(3-二茂铁基-2-巴豆酸,HOOC-CH˭(CH3)CFc (Fc˭(η5-C5H5)Fe(η5-C5H4))或邻二茂铁羰基苯甲酸, o-HOOCC6H4COFc 和 2,2'-联吡啶 (2,2'-bipy) 与 ZnCl2 · 2H2O 或 Zn(OAc)2 · 2H2O 生成两种含二茂铁的络合物 [ZnCl(η2-OOCCH˭(CH3)CFc)( 2,2'-bipy)] (1) 和 [Zn(η2-o-OOCC6H4COFc) (o-OOCC6H4COFc)(2,2'-bipy)] · 1.5H2O (2)。 X 射线测定。两种配合物中有金属离子、二茂铁基取代的羧酸根单元和 2,2'-bipy 三种成分。这种含有二茂铁基取代的羧酸根和联吡啶基配体的配合物很少见。测定了配合物的状态差分脉冲伏安法。结果表明,二茂铁基部分的半波电位受 Zn(II) 离子的影响。
