双二茂铁-钯配合物的合成,结构和电化学(英文)

Synthesis, Crystal Structure and Electrochemistry of Biferrocene Palladium Complex

本文讨论了由二茂铁的C-H…π作用组装的具有类环己烷结构的氨基硫脲钯金属配合物的结构和电化学性能。晶体结构中钯原子以顺式平面正方形的构型分别与两个氨基硫脲配体配位,两个配体中的二茂铁基团位于钯原子同一侧,每个二茂铁与相邻分子中的二茂铁基团通过环戊二烯基环间的C-H…π作用形成由类环己烷结构连结的二维网状结构。对钯的配合物及相关的镍和锌配合物的电化学研究表明,平面正方型的钯和镍可以有效的传递两个茂铁间的氧化-还原性能。

A new supramolecular cyclohexane-like structure [PdL2](6)(HL = acetylferrocenyl thiosemicarbazone) has been constructed by self-assembly of ferrocene moieties via C - H...pi interactions. The palladium (II) atom is coordinated in a distorted square-planar cis-configuration in which two ferrocene-containing ligands positioned on the same side. Each ferrocene moieties interacts with symmetry-related species to form a two dimensions supramolecular network. Electrochemical measurements of [PdL2], [NiL2] and [ZnL2] compounds indicate that the square planar configuration of the Ni (II) and Pd (II) moieties, can effectively transmit the redox effects of the ferrocene moieties.
