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

Abstract

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 in situ generated and presynthesized cis-[Os](H)–CC–R units in these frameworks act as organometallic bidentate chelating ligands coordinating with the AgPPh₃ cation, which makes these complexes more stable. Our results provide a new synthetic route for the construction of stable heterobimetallic complexes.
