摘要：
A hydrido(dihydrosilyl) platinum(II) complex having PMe(3)ligands, [cis-PtH(SiH(2)Trip)(PMe3)(2)] (2) (Trip = 9-triptycyl) was prepared by the ligand-exchange reaction of [PtH(SiH2 Trip)-(PMe3)(PPh3)] (1) with an excess amount of free PMe3 in hexane. X-ray crystallographic analysis of 2 revealed that the platinum center adopts a twisted square-planar geometry; the dihedral angle between the P-Pt-P and Si-Pt-H planes is 10.43 degrees. The complex displayed a fluxional NMR behavior in solution on the NMR time scale, where a eta(1) -Si-H structure was suggested as a transition state of the rate-controlling step by DFT calculation.
