Abstract

1,4-Bis(dimethylsilyl)benzene reacted with [Pt₃H(PEt ₃)₃(μ-PPh₂)₃] at room temperature to yield trinuclear Pt complex [Pt₃(SiMe₂C ₆H₄SiMe₂H)(PEt₃)₂(μ- PPh₂)₃] (1a). Heating a solution containing an equimolar mixture of [Pt₃H(PEt₃)₃(μ-PPh ₂)₃] and 1a at 60 °C produced a hexanuclear Pt complex [(PEt₃)₂(μ-PPh₂)₃Pt ₃(SiMe₂C₆H₄SiMe₂)Pt ₃(PEt₃)₂(μ-PPh₂)₃] (2a). Complex 1a was characterized by X-ray crystallography and NMR spectroscopy, while the structure of 2a was determined by X-ray crystallography of single crystals containing 2a and [Pt₃H₂(PEt ₃)₂(μ-PPh₂)₄] in 1:1 ratio. [Pt₃(SiMe₂fcSiMe₂H)(PEt₃) ₂(μ-PPh₂)₃] (fc = Fe(η⁵- C₅H₄)₂) (1b) and [(PEt₃) ₂(μ-PPh₂)₃Pt₃(SiMe ₂fcSiMe₂)Pt₃(PEt₃) ₂(μ-PPh₂)₃] (2b) were obtained similarly from the reactions of 1,1′-bis(dimethylsilyl)ferrocene with [Pt ₃H(PEt₃)₃(μ-PPh₂)₃] and characterized by NMR spectroscopy and elemental analyses.
