介绍了一系列对称双核配合物的结构和电化学行为，其中两个铁中心由三个双[4-(4'-甲基-2,2'-联吡啶基)]烷配体桥接。方波伏安法用于表征以金属为中心的半部之间相互作用的程度。由于饱和键排除了显着的电子离域，因此观察到的相互作用本质上几乎是纯粹的库仑相互作用。此外，分子模型和X射线晶体学数据证实，在键中包含三个亚甲基的复合物中的铁-铁分离几乎与在键中包含两个亚甲基的复合物中的铁-铁分离几乎相同。使用简单的静电模型并采用从 X 射线数据和分子建模获得的结构参数，解释了该系列中的电化学趋势。
The structures and electrochemical behavior of a series of symmetric dinuclear complexes in which two iron centers are bridged by three bis[4-(4'-methyl-2,2'-bipyridinyl)]alkane ligands are presented. Square wave voltammetry was used to characterize the extent of interaction between the metal-centered halves. Because the saturated linkages preclude significant electron delocalization, the observed interaction is concluded to be almost purely Coulombic in nature. Furthermore, molecular modeling and X-ray crystallographic data confirm that the iron-iron separation in the complex containing three methylenes in the linkages is nearly identical to the ironiron separation in the complex containing two methylenes in the linkages. Using a simple electrostatic model and employing structural parameters obtained from X-ray data and molecular modeling, the electrochemical trends within the series are interpreted.
