چکیده
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 th 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 m3-oxo ligand of a cation of 1, the hydroxyl group of the second acid functio interacting with a tetrafluoroborate anion. With trimesic acid, a 1:2 (acid:cluster) supramolecular system is formed. Two hydroxyl group interact with the m3-oxo ligand of two independent cations of 1, while the remaining hydroxyl group of the third acid function interacts with tetrafluoroborate anion.

The synthesis of [Cu3O(OAc)6(H2O)3]Cl.CH3OH.6H2O is described. The X-ray crystallographic study of thecomplex revealed an isosceles triangle of copper atoms with a triply bridging oxo atom nearly in the plane of thetriangle. The coordination sphere around each metal center is close to distorted octahedral and the central{Cu3(μ3-O)} core is planar. Every two copper atoms were connected to each o...
