摘要：

Reaction of(IMP)SiH3 with (PhnMe3-nP)(2)PtMe2 at 50 degreesC provided the dinuclear complexes trans-[(PhnMe3-nP)(2)Pt(mu -SiHAr)](2) [Ar = 2-isopropyl-6-methylphenyl (IMP)]. These complexes were characterized by multinuclear NMR and IR spectroscopy and X-ray crystallography. The Si-29 NMR chemical shift for {PhMe2P)(2)Pt[mu -SiH(IMP]}(2) appears at unusually high field (-134 ppm) for complexes containing bridging silylene moieties. The X-ray structures of these complexes reveal acute Si-Pt-Si and obtuse Pt-Si-Pt angles. In solution, {(Ph2MeP)(2)Pt[mu -SiH(IMP)]}(2) undergoes dissociation of PMePh2 down to - 90 degreesC.
