Résumé
Reaction of [Ru(?6-indan)(H2O)3]2+ and [Ru(?6-C6Me6)(H2O)3]2+ with NaBH4 in water gives a mixt. of three triple hydrido-bridged arene ruthenium cations [(?6-arene)Ru(?-H)3Ru(?6-arene')]+ (arene = indan and hexamethylbenzene; arene' = indan and hexamethylbenzene). After treatment with NaBF4, the three complexes are sepd. by column chromatog. and the unsym. cation [(?6-indan)Ru(?-H)3Ru(?6-C6Me6)][BF4] can be isolated in moderate yield. This cation decomps. in soln. to give the corresponding hydroxo-bridged complex [(?6-indan)Ru(?-OH)3Ru(?6-C6Me6)]+ with retention of the unsym. geometry as shown by single-crystal X-ray anal. The indan ligand adopts an envelope conformation toward the ruthenium atom. [on SciFinder(R)]
