σ-GeH and Germyl Cationic Pt(II) Complexes.

ABSTRACT: The low electron count Pt(II) complexes [Pt(NHC')(NHC)][BAr^F] (where NHC is a N-heterocyclic carbene ligand and NHC' its metalated form) react with tertiary hydrogermanes HGeR₃ at room temperature to generate the 14-electron platinum(II) germyl derivatives [Pt(GeR₃)(NHC)₂][BAr^F]. Low-temperature NMR studies allowed us to detect and characterize spectroscopically some of the σ-GeH intermediates [Pt(η²-HGeR₃)(NHC')(NHC)][BAr^F] that evolve into the platinum-germyl species. One of these compounds has been characterized by X-ray diffraction studies, and the interaction of the H-Ge bond with the platinum center has been analyzed in detail by computational methods, which suggest that the main contributi
