Résumé
The new triple-bridged dinuclear cation [(η<sup>6</sup>-C<sub>6</sub>Me<sub>6</sub>)<sub>2</sub>Ru<sub>2</sub>(μ<sub>2</sub>-p-S-C<sub>6</sub>H<sub>4</sub>-OH)(μ<sub>2</sub>-PPh<sub>2</sub>)(μ<sub>2</sub>-H)]<sup>+</sup>, isolated and characterized as the tetrafluoroborate salt, was prepared by reacting the precursor [(η<sup>6</sup>-C<sub>6</sub>Me<sub>6</sub>)<sub>2</sub>Ru<sub>2</sub>(μ<sub>2</sub>-H)<sub>2</sub>(μ<sub>2</sub>-PPh<sub>2</sub>)](BF<sub>4</sub>) and <i>p</i>-hydroxythiophenol in refluxing ethanol. The single-crystal X-ray structure analysis of [(η<sup>6</sup>-C<sub>12</sub>H<sub>18</sub>)<sub>2</sub>Ru<sub>2</sub>(μ<sub>2</sub>-S-C<sub>6</sub>H<sub>4</sub>-OH)(μ<sub>2</sub>-H){μ<sub>2</sub>-<sub>P</sub>(C<sub>6</sub>H<sub>5</sub>)<sub>2</sub>}](BF<sub>4</sub>) shows the formation of the <i>meso</i> form; despite the two stereogenic centres the complex is not chiral.
