Genesis of electron deficient Pt1(0) in PDMS-PEG aggregates.

ABSTRACT: While numerous single atoms stabilized by support surfaces have been reported, the synthesis of in-situ reduced discrete metal atoms weakly coordinated and stabilized in liquid media is a more challenging goal. We report the genesis of mononuclear electron deficient Pt₁(0) by reducing H₂PtCl₆ in liquid polydimethylsiloxane-polyethylene glycol (PDMS-PEG) (Pt₁@PDMS-PEG). UV-Vis, far-IR, and X-ray photoelectron spectroscopies evidence the reduction of H₂PtCl₆. CO infrared, and ¹⁹⁵Pt and ¹³C NMR spectroscopies provide strong evidence of Pt₁(0), existing as a pseudo-octahedral structure of (R¹OR²)₂Pt(0)Cl₂H₂ (R¹ and R² ar
