Résumé
The thermal reaction of Ru<sub>3</sub>(CO)<sub>12</sub> with various carboxylic acids (benzoic, 4-hydroxyphenylacetic, ferrocenic, stearic, oleic, 4-(octadecyloxy)benzoic) in refluxing tetrahydrofuran, followed by addition of 5-(4-pyridyl)-10,15,20-triphenylporphyrin (L), gives the dinuclear complexes Ru<sub>2</sub>(CO)<sub>4</sub>(OOCR)<sub>2</sub>L<sub>2</sub> (<b>1</b>: R = –C<sub>6</sub>H<sub>5</sub>, <b>2</b>: R = –CH<sub>2</sub>-<i>p</i>-C<sub>6</sub>H<sub>4</sub>OH, <b>3</b>: R = –C<sub>5</sub>H<sub>4</sub>FeC<sub>5</sub>H<sub>5</sub>, <b>4</b>: R = –(CH<sub>2</sub>)<sub>16</sub>CH<sub>3</sub>, <b>5</b>: R = –(CH<sub>2</sub>)<sub>7</sub>CHdouble bond; length as m-dashCH(CH<sub>2</sub>)<sub>7</sub>CH<sub>3</sub>, <b>6</b>: R = –<i>p</i>-C<sub>6</sub>H<sub>4</sub>O(CH<sub>2</sub>)<sub>17</sub>CH<sub>3</sub>). Complexes <b>1–6</b> were characterised by IR, NMR, and ESI-MS as well as by elemental analysis. The UV–Vis spectra show the Soret band centred at 417 nm and the Q bands at 515, 550, 590 and 645 nm, respectively.
