    Summary
    The hydrogen-bonded systems formed between 5-bromo-isophthalic and trimesic acid derivatives and the trinuclear arene-ruthenium cluster cation [H3Ru3(C6H6)(C6Me6)2 (O)]+ (1) 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 [1][BF4] shows a 1:1 (acid:cluster) supramolecular system, only one hydroxyl of the acid functions interacting with the μ3-oxo ligand of a cation of 1, 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 μ3-oxo ligand of two independent cations of 1, while the remaining hydroxyl group of the third acid function interacts with a tetrafluoroborate anion.
