Kinetically stabilized 1,2-dibromodisilene, Bbt(Br)SiSi(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)SiPt(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.
