A Lead-μ<sub>2</sub>-Tetrylide Complex with Osmium(IV) Terminal Components
A bare lead atom is a σ-donor ligand capable of linearly bonding and stabilizing two units of a classical polyhydride complex, with a high-valent metal center. As a proof of concept, we have prepared and characterized the μ<sub>2</sub>-tetrylide complex (P<sup>i</sup>Pr<sub>3</sub>)<sub>2</sub>H<sub>4</sub>Os═Pb═OsH<sub>4</sub>(P<sup>i</sup>Pr<sub>3</sub>)<sub>2</sub> in the reaction of OsH<sub>6</sub>(P<sup>i</sup>Pr<sub>3</sub>)<sub>2</sub> with Pb{N(SiMe<sub>3</sub>)<sub>2</sub>}<sub>2</sub>. Although the Pb-Os bonds exhibit electrostatic interaction, the main orbital interactions result from two dative σ bonds from the lead atom to the osmium centers. The latter also provide much weaker π-backdonations.
