In this project supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program, Derek J. Hodgson of the University of Wyoming will investigate the synthesis of binuclear coordination compounds of manganese in moderately high oxidation states. The structures, oxidation-reduction properties and the electrochemical behavior of these complexes will be examined. The compounds may be useful as electrocatalytic oxidants. They are also of interest bcause they are related to the manganese compounds of Photosystem II, which is involved in photosynthesis. The complexes to be investigated are mu-dioxo dimers of manganese(III/III), manganese(III,IV) and manganese(IV,IV) with auxiliary tetradentate ligands containing four nitrogen donor atoms. These non-porphyrinic ligands will be modified with various substituents and other structural changes so as to cause the redox behavior of the complexes to vary in a predictable manner.

在这个由无机、生物无机和有机金属化学项目支持的项目中，怀俄明大学的德里克·j·霍奇森将研究在中等高氧化态下锰的双核配位化合物的合成。研究了这些配合物的结构、氧化还原性能和电化学行为。该化合物可作为电催化氧化剂使用。它们也引起了人们的兴趣，因为它们与参与光合作用的光系统II的锰化合物有关。所研究的配合物是锰（III/III），锰（III，IV）和锰（IV，IV）与含有四个氮给体原子的辅助四齿配体的mu-二氧二聚体。这些非卟啉配体将被各种取代基和其他结构变化修饰，从而使配合物的氧化还原行为以可预测的方式变化。
