Taking advantage of ligand sets jointly developed and utilised previously for symmetrical dinuclear and trinuclear ligand-bridged mixed-valent systems we intend to introduce various degrees of asymmetry via modified bridging ligands or asymmetrically arranged co-ligands in order to study the valence exchange in non-degenerate systems. These investigations will involve mixed-valence isomers and the analysis of directed flow of charge and electrons on excitation or (electro)chemically induced electron transfer. New complexes of ruthenium or osmium and less common unsaturated ligands involving N, O and S donor atoms will be synthesised, characterised and investigated with spectroscopic, (spectro)electrochemical and magnetic resonance techniques. The results which will extend the existing highly productive cooperation between the partners are expected to be of significance for molecular electronic concepts.

利用配体集联合开发和利用以前的对称双核和三核配体桥接的混合价体系，我们打算引入不同程度的不对称性，通过修改桥接配体或不对称排列的共配体，以研究非简并系统中的价交换。这些调查将涉及混合价异构体和电荷和电子的激发或（电）化学诱导的电子转移的定向流动的分析。钌或锇和不太常见的不饱和配体，涉及N，O和S供体原子的新的配合物将合成，其特征在于和研究与光谱，（光谱）电化学和磁共振技术。这些结果将扩展合作伙伴之间现有的高效合作，预计对分子电子概念具有重要意义。
