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.
