Résumé
The hydrogen-bonded systems formed between 5-bromo-isophthalic and trimesic 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 the solid state by single-crystal X-ray structure analysis of the tetrafluoroborate salts. The structure analysis of 5-bromo-isophthalic acid with [<b>1</b>][BF<sub>4</sub>] shows a 1:1 (acid:cluster) supramolecular system, only one hydroxyl of the acid functions interacting with the μ<sub>3</sub>-oxo ligand of a cation of <b>1</b>, the hydroxyl group of the second acid function interacting with a tetrafluoroborate anion. With trimesic acid, a 1:2 (acid:cluster) supramolecular system is formed. Two hydroxyl groups interact with the μ<sub>3</sub>-oxo ligand of two independent cations of <b>1</b>, while the remaining hydroxyl group of the third acid function interacts with a tetrafluoroborate anion.
