Ruthenium(III) complexes are known for their high stability and inertness. To the best of our knowledge, the only well-characterized example of a labile Ru(III) complex is [RuIII(edta)(H2O)] as a 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. Compelling experimental evidence is presented demonstrating that the [RuIII(phtpy)Cl3] complex is labile, also indicating that the Ru(III)–phtpy bond is much weaker than expected, in contrast to the strongly π-back-bonding stabilized Ru(II)–phtpy bond.

[Ru III（phtpy）Cl 3 ]配合物的意外稳定性
钌（III）配合物以其高稳定性和惰性而著称。据我们所知，不稳定的Ru（III）配合物的唯一特征充分的例子是[Ru III（edta）（H 2 O）]，这是由于分子内氢键导致形成大的开口在分子前沿，因此将机理从解离改变为缔合。提出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。
