title = "Dynamic stereochemistry of cis-[PtH(SiR3)(PPh3) 2]. Spontaneous ligand interchange with retention of nuclear spin-spin correlation",
abstract = "Above 0 °C in various solvents the complexes cis-[PtH(SiR3) (PPh3)2] with R = C6H5, p-ClC 6H4, or p-MeC6H4 undergo spontaneous interchange of the PPh3 ligand positions by a mechanism which retains P ⋯(Pt) ⋯ H spin correlation and is thus intramolecular and non-dissociative within the limits of the n.m.r. experiment.",

note = "Funding Information: shows the efTect of adding 107; PPh,. include formation of associated molecular pairs such as [(Ph,P)PtH(SiR,)].PPh, or [(Ph,P),Pt]-HSiR3. The latter is similar to a recent suggestion to account for the properties of [MnH(SiPh,)(~5-C5H,)(C0)2].6Another interesting possibi- n lity is rotation of an intermediate, R3Si--H--ML2; structures involving bridging hydrogen on an M-Si bond have been proposed for several metals (Mn, Re, Pt) but definitive evi-dence has proved el~sive.~?{\textquoteright} We thank the University of Kuwait for a student grant (N.M.S.), the Caixa de Barcelona for a research fellowship (J.V.), and the University of Victoria for study leave funding (K.R.D .).
