Palladium-platinum heterobimetallic complexes with bridging silicon ligands. Structure and reaction with isonitrile to afford a platinacyclopentane containing Si, N, and C atoms

The reaction of Pt(SiHPh2)2(PEt3) 2 with Pd(PEt3)3 produced heterodinuclear complexes with bridging diphenylsilyl ligands (Et3P)Pt(μ- η2-SiHPh2)2Pd(PEt3) (1) and (Et3P)2Pt(μ-η2-SiHPh2) 2Pd(PEt3) (2). Each product was isolated and fully characterized. X-ray crystallography of 2 and NMR spectra of 2 and 2-d 2 at 25 °C indicated the presence of two bridging SiHPh 2 (or SiDPh2) ligands, which were bonded to one metal center via a M-Si single bond and to the other via a Si-H-M three-center, two-electron bond. The 1H NMR spectrum of 2 at -90 °C exhibited a peak atδ -8.61 due to a hydrido ligand bonded to the Pt center, indicating the structure (Et3P)2PtH(μ-SiPh 2)(μ-η2-SiHPh2)Pd(PEt3) in the solution at low temperature. Complex 2 reacted with CN-t-Bu to form a mixture of (Et3P)(t-BuNC)-Pt(SiPh2-CH2-N(t-Bu)- SiPh2) (3) and [(Et3P)(t-BuNC)Pt(μ-SiPh 2)]2 (4). Complex 3 contained the platinacyclopentane group, whose five-membered ring was composed of Pt, Si, N, and C atoms.
