Résumé
The hydrogen-bonded systems formed between monocarboxylic acid derivatives and the trinuclear arene-ruthenium cluster cation [H<sub>3</sub>Ru<sub>3</sub>(C<sub>6</sub>H<sub>6</sub>)(C<sub>6</sub>Me<sub>6</sub>)<sub>2</sub>(O)]<sup>+</sup> (<b>1</b>) have been studied in solution by cold-spray ionisation mass spectroscopy (CSI-MS) and in the solid state by single-crystal X-ray structure analysis of the tetrafluoroborate salts. The presence of 1:1 (acid:cluster) adducts in acetone solution has been clearly demonstrated by CSI-MS. Single-crystal X-ray structure analyses of selected acid-cluster complexes show that in every case the hydroxyl of the acid function interacts strongly with the μ3-oxo ligand of cation <b>1</b>, the O <b>…</b> O distance ranging from 2.499(9) to 2.595(11) <b>Å</b>.
