Abstract

Heterobimetallic cores are important units within the active sites of metalloproteins but are often difficult to duplicate in synthetic systems. We have developed a synthetic approach for the preparation of a complex with a Mn(II)-(μ-OH)-Fe(III) core, in which the metal centers have different coordination environments. Structural and physical data support the assignment of this complex as a heterobimetallic system. A comparison with analogous homobimetallic complexes, Mn(II)-(μ-OH)-Mn(III) and Fe(II)-(μ-OH)-Fe(III) cores, further supports this assignment.

摘要

杂双核是金属蛋白活性中心的重要单元，但在合成体系中往往难以复制。我们开发了一种合成方法，用于制备具有 Mn(II)-(μ-OH)-Fe(III)核的配合物，其中金属中心具有不同的配位环境。结构和物理数据支持将该配合物指定为杂双核体系。与类似的同双核配合物 Mn(II)-(μ-OH)-Mn(III)和 Fe(II)-(μ-OH)-Fe(III)核的比较进一步支持了这一分配。
