Facile synthesis of air-stable heterobimetallic osmium-silver hydride complexes.

The synthesis and characterization of air-stable heterobimetallic Os-Ag hydrides are described. All of the new heterobimetallic Os-Ag hydrides are neutral, and the generated and presynthesized -[Os](H)-CC-R units in these frameworks act as organometallic bidentate chelating ligands coordinating with the AgPPh cation, which makes these complexes more stable. Our results provide a new synthetic route for the construction of stable heterobimetallic complexes.
