ChemInform Abstract: Hydrogen Atom Abstraction from C‐H, P‐H, Si‐H, and Sn‐H Bonds by the Triplet Excited State of the Tetrakis(μ‐pyrophosphito)diplatinum(II) Tetraanion. Spectroscopic Observation of the Mixed‐Valence Hydride Complex Pt2(μ‐P2O5H2)4H4‐.

Abstract

The Pt(II)Pt(III) hydride complex Pt2(μ‐P2O5H2)4H4‐ (I) can be generated by either pulse radiolysis of aqueous Pt2(μ‐P2O5H2)44‐ (II) at pH 4 in the presence of t‐BuOH or by pulsed‐laser photolysis (Nd‐YAG at 355 nm) or aqueous (II) with added i‐PrOH, H3PO3, or H3PO2.
