Resumo

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 {[}Ru-III(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 {[}Ru-III(phtpy)Cl-3] complex is labile, also indicating that the Ru(III) phtpy bond is much weaker than expected, in contrast to the strongly pi-back-bonding stabilized Ru(II)-phtpy bond.
