The novel compound 1,2-bis(diphenylphosphino)ethane)-hydrido-(triphenyltin)-platinum, (dppe)PtH(SnPh3), has been successfully synthesized and structurally characterized. This work is part of a larger project studying the platinum tin hydride core to better understand the catalytic chemistry of organobimetallic compounds. The synthesis (eq 1) and solution state structure as determined by multinuclear NMR spectroscopy will be discussed (1JSnPt = 11364 Hz, 1JHPt = 903 Hz, 1JPtP" = 2354 Hz, 1JPtP' = 2079 Hz, where P' refers to the phosphorus trans to the hydride and P" refers to the phosphorus cis to the hydride). The solid state structure shows three unique molecules in the unit cell (Figure 1), with Pt-Sn bond lengths of 2.599(2) Å, 2.586(2) Å, and 2.593(2) Å. These structures will be discussed in terms of the solution state NMR parameters and DFT calculations.
