Isolation and characterization of the dimetal decacarbonyl dication [Ru <sub>2</sub> (CO) <sub>10</sub> ] <sup>2+</sup> and the metal-only Lewis-pair [Ag{Ru(CO) <sub>5</sub> } <sub>2</sub> ] <sup>+</sup>
The reaction of Ag<sup>+</sup> with Ru<sub>3</sub>(CO)<sub>12</sub> in a CO atmosphere under concommittant irradiation with UV-light yields a salt of the metal-only Lewis-pair [Ag{Ru(CO)<sub>5</sub>}<sub>2</sub>]<sup>+</sup>. Switching the silver cation for a more process-selective deelectronator yields a salt of the homoleptic transition metal carbonyl cation [Ru<sub>2</sub>(CO)<sub>10</sub>]<sup>2+</sup>, which fills the gap between the known cations [Ru(CO)<sub>6</sub>]<sup>2+</sup> and [Ru<sub>3</sub>(CO)<sub>14</sub>]<sup>2+</sup>. The amount of π-backdonation in this series was studied by a combination of vibrational spectroscopy and computed relaxed force constants.
