Abstract

The reaction of tetraiododiborane (B₂ I₄ ) with trans-[Pt(BI₂ )I(PCy₃ )₂ ] gives rise to the diplatinum(II) complex [{(Cy₃ P)(I₂ B)Pt}₂ (μ₂ :η³ :η³ -B₂ I₄ )], which is supported by a bridging diboranyl dianion ligand [B₂ I₄ ]^2- . This complex is the first transition-metal complex of a diboranyl dianion, as well as the first example of intact coordination of a B₂ X₄ (X=halide) unit of any type to a metal center.

Keywords: boron; diboranes; haloboranes; platinum; σ-bond complexes.
