Question:

The complex [PtH(PEt₃)₃]⁺ was studied in deuterated acetone in the presence of excess PEt₃. In the absence of excess ligand the ¹H-NMR spectrum in the hydride region exhibits a doublet of triplets. As excess PEt₃ ligand is added the hydride signal begins to change, the line shape depending on the ligand concentration. Suggest a mechanism to account for the effects of excess PEt₃.
