| Abstract: | The reaction of tetraiododiborane (B2I4) with trans‐[Pt(BI2)I(PCy3)2] gives rise to the diplatinum(II) complex [{(Cy3P)(I2B)Pt}2(μ2:η3:η3‐B2I4)], which is supported by a bridging diboranyl dianion ligand [B2I4]2?. This complex is the first transition‐metal complex of a diboranyl dianion, as well as the first example of intact coordination of a B2X4 (X=halide) unit of any type to a metal center. |
