Kinetically stabilized 1,2-dibromodisilene, Bbt­(Br)­SiSi­(Br)­Bbt (Bbt = 2,6-bis­[bis­(trimethylsilyl)­methyl]-4-[tris­(trimethylsilyl)­methyl]­phenyl) (2), was treated with [Pt­(PCy3)2] to afford the corresponding arylbromosilylene–Pt complex, Bbt­(Br)­SiPt­(PCy3)2 (1), as stable orange crystals. The molecular structure of 1 was elucidated by spectroscopic and X-ray crystallographic analyses. The nature of the Si–Pt bond in 1 was investigated with the aid of DFT calcualtions.
