  Ruthenium(III) complexes are known for their high stability and inertness. To the best of out knowledge, the only well characterized example of labile Ru(III) complex is [RuIII(edta)(H2O)] as consequence of an intramolecular hydrogen bonding leading to the formation of a large opening in the molecule front, thus changing the mechanism from dissociative to associative. Here compeling experimental evidences

  钌（III）配合物以其高稳定性和惰性而著称。据其所知，不稳定的Ru（III）络合物唯一具有良好特征的例子是[Ru III（edta）（H 2 O）]，这是分子内氢键导致在分子中形成大开口的结果前，从而将机制从分离变为联合。在此提供了令人信服的实验证据，表明[Ru III（phtpy）Cl 3 ]络合物不稳定，也表明Ru（III）-phtpy键比预期的弱得多，与强π-背键稳定的Ru相反（II）-phtpy键

• Intramolecular electron transfer in photoexcited ruthenium(II)-rhodium(III) binuclear compounds
  作者：Koichi Nozaki、Takeshi Ohno、Masaaki Haga

  DOI：10.1021/j100205a051

  日期：1992.12

  Lifetimes of metal-to-ligand charge-transfer excited states, (3CT)Ru, of ruthenium(II) were measured for ruthenium(II)-rhodium(III) compounds, [Ru(bpy)2(L-L)Rh(bpy)2]5+, and its analogous compounds in a wide temperature range (170-300 K) in the fluid solvent of a mixture of propionitrile and butyronitrile. The interventing ligands (L-L) used were 2,6-bis(2'-pyridyl)benzdiimidazole (dpimbH-2), 2,2'-bis(2''-pyridyl)bibenzimidazole (bpbimH-2), 1,1'-dimethyl-2,2'-bis(2''-pyridyl)-6,6'-bibenzimidazole (dmbpbim), and bis[2-(2'-pyridyl)benzimidazoyl]ethane (dpbime). The rapid quenching of (3CT)Ru can be explained in terms of an intramolecular electron transfer (ET), (3CT)Ru-Rh(III) --> Ru(III)-Rh(II), which is followed by a fast backward ET to regenerate the ground state. The frequency factors obtained from the temperature dependence of the ET rates were found to be almost constant, (1.1-4.1) x 10(11) s-1, irrespective of the intervening ligands, indicating that the ET processes are adiabatic. These factors were in agreement with the value (4-6) x 10(11) s-1 calculated provided that the ET is influenced by the relaxation dynamics of the solvent. The activation energy (E(a)) ranged from 0.17 to 0.22 eV depending on the bridging ligands. Using the reorganization energy, lambda, determined from the metal-to-metal charge-transfer transition of a mixed-valence compound, [Ru(bpy)2(L-L)Ru(bpy)2]5+, E(a) was evaluated on the basis of the classical ET theory. The E(a) values calculated by considering the temperature dependence of lambda and the solvent motion were in good agreement with the observed values except for bpbimH-2.
