Synthesis and characterization of an iridium–bismuth metallaheterocycle

Heavy atom metallaheterocycles are an emerging family of new complexes that exhibit new structures and interesting chemical properties. In this work, the iridium–bismuth heterocyclic complex, [Ir4(CO)10(μ-BiPh2)(μ-H)]2, 1 has been obtained from the reaction of [PPN][HIr4(CO)11] with Ph2BiCl. Compound 1 was structurally characterized and was found to contain two centrosymmetrically-related Ir4(CO)10(μ-H) clusters linked by two bridging BiPh2 ligands positioned on opposite sides of a planar six-membered Ir4Bi2 ring.

The iridium–bismuth complex [Ir4(CO)10(μ-BiPh2)(μ-H)]2,1 was obtained from the reaction of [HIr4(CO)11]− anion with Ph2BiCl. Complex 1 contains a planar, six-membered Ir4Bi2 ring composed of two tetrahedral [HIr4(CO)11] clusters linked by two bridging BiPh2 ligands.Figure optionsDownload as PowerPoint slide
