Résumé
The trinuclear arene-ruthenium cluster cations [H3Ru3(C6H6)(C6H2Me4)2(O)]+ (2) and [H3Ru3{C6H5(CH2)2OH}(C6H2Me4)2(O)]+ (3) have been synthesized from the dinuclear precursor [H3Ru2(C6H2Me4)2]+ (1) and the mononuclear complexes [Ru(C6H6)(H2O)3]2+ and [Ru{C6H5(CH2)2OH}(H2O)3]2+, isolated, and characterized as the tetrafluoroborate salts. Cations 2 and 3 are analogs of the cluster cation [H3Ru3(C6H6)(C6Me6)2(O)]+ which was found to catalyze the hydrogenation of benzene to give cyclohexane under biphasic conditions ('supramol. cluster catalysis'). The single-crystal X-ray structure analyses of 2 and 3 have been detd. Unlike [2][BF4]·3H2O, [3][PF6]·H2O shows a dimeric structure in the solid state, thanks to hydrogen bonds between the hydroxo function of one mol. of 3, a water mol. and the oxo cap of an other mol. of 3.
