Résumé
1,1′-Ferrocene dicarboxylic acid pyridin-4-yl ester (<b>1</b>) is prepared from 1,1′-ferrocene dicarbonyl chloride and 4-hydroxypyridine. This new bidentate ferrocenoyl ligand reacts with the monocationic complex [(η<sup>6</sup>-<i>p</i>-cymene)<sub>2</sub>Ru<sub>2</sub> (μ-OH)<sub>3</sub>]<sup>+</sup> to give the dicationic complex [(η<sup>6</sup>-<i>p</i>-cymene)<sub>2</sub>Ru<sub>2</sub>(μ-OH)<sub>2</sub>(1,1′- (NC<sub>5</sub>H<sub>4</sub>–OOC)<sub>2</sub>–Fc)]<sup>2+</sup> (<b>2</b>) (Fc: C<sub>5</sub>H<sub>4</sub>–Fe–C<sub>5</sub>H<sub>4</sub>), isolated as a tetrafluoroborate salt. The single-crystal X-ray structure analysis of [<b>2</b>][BF<sub>4</sub>] <sub>2</sub> reveals the ferrocenoyl pyridine ligand <b>1</b> to act as μ<sub>2</sub>-η<sup>2</sup> chelating ligand in the dinuclear complex, having replaced a μ<sub>2</sub>-η<sup>1</sup>-hydroxo ligand.
