1. ^<99>Ru NMR of Ru (III) Dimer and Related Compounds. ^<99>Ru NMR spectra have been measured on senen Ru (III) polynuclear complexes, which are essentially diamagnetic through Ru (III)-Ru (III) interaction. Effects of oxidation sate, donor atom, and metal-metal bond upon chemical shift have been studied.2. Synthesis and Characterization of Carboxylate Bridged Polynuclear Complexes. More than 20 new compounds have been synthesized, and their properties have been studied from the view point of the assemblage effects.(1) Novel Pt (III) dimers in which CH_2COO^<2-> bridges two Pt's through C and O have been synthesized.(2) In a pyrazine bridged dimer of the oxo, carboxylato bridged Ru trinuclear cluster, we produced successfully "mixed valence" states between the trinuclear units.(3) We found that large (20-26) membered Curtis macrocycles (fully saturated form) act as a dinucleating ligand for Cu (II) by taking up two additional small bridging ligands such as OR^-, OH^-, or CH_3COO^-. Such Cu (II) dimers show generally anti-ferromagnetic interaction. The degree of the interaction was found to be very sensitive to the core structure of the dimer.(4) A new photo-induced ligand substitution was found in oxo, carboxylato bridged trinuclear Ru complexes with the CO terminal ligand.3. Synthesis of Macromolecular Complexes having Trinuclear Ru Cluster Unit. Six new macromolecular complexes comprised of 4-polyvinylpyridine and oxo, carboxylato bridged Ru trinuclear cluster have been synthesized. Under certain conditions, thin film of the complex coated on a glassy carbon electrode showed reversible redox response in an aqueous solution.

1。 ^<99> Ru NMR光谱已经在Senen Ru（III）多核复合物上进行了测量，这些复合物基本上是通过RU（III）-RU（III）相互作用的磁性磁性的。已经研究了氧化剂，供体原子和金属金属键对化学位移的影响2。羧酸盐桥接多核复合物的合成和表征。已经合成了20多种新化合物，并从组合效应的角度研究了它们的特性。（1）新型Pt（iii）二聚体，其中CH_2COO^<2->桥接两个Pt和O合成了两个PT和O。价值“三核单元之间的状态。（3）我们发现，大型（20-26）成员的柯蒂斯大环（完全饱和的形式）用作Cu（ii）的二核配体，通过摄取另外两个其他的小桥式配体，例如或^ - ，OH^ - ，OH^ - 或CH__3COO^ - 。这种Cu（II）二聚体通常显示出抗铁磁相互作用。发现相互作用的程度对二聚体的核心结构非常敏感。（4）在Oxo，羧基桥桥的三核RU复合物中，与CO末端配体发现了新的照片诱导的配体取代。3。具有三核RU簇单元的大分子复合物的合成。已合成了六种由4-聚乙烯基吡啶和氧甲基甲基桥接的RU三核簇组成的新的大分子复合物。在某些条件下，在玻璃碳电极上涂层的复合物的薄膜在水溶液中显示出可逆的氧化还原反应。
