heterobimetallic species of interest, M+[M′M″(CO)9L]− (M+ = Na+; M′ Cr, W; M″ Mn, Re; L CO, PR3) undergoes ligand substitution or metal-metal bond cleavage upon reaction with PR3 (R C6H5, C2H5) or CO. Unprecedented reactions by the counter ion were observed. Factors affecting these dimeric disruptions will be discussed on the basis of the kinetic studies.
异双金属配合物具有供体-受体金属-金属键,其中来自富电子金属部分的两个电子被提供给另一个缺电子的金属部分。感兴趣的杂双金属物质M + [M'M''(CO)9 L] -(M + = Na +; M'Cr,W; M“Mn,Re; LCO,PR 3)经历配体在与PR反应取代或金属-金属键断裂3(Rç 6 ħ 5,C 2 H ^ 5)或CO。由抗衡离子前所未有的反应中观察到。将在动力学研究的基础上讨论影响这些二聚体破坏的因素。
