Abstract
Mechanochemical treatment of solid-phase K2PtX6 salts in a vibrating mill in an argon or air atmosphere produced paramagnetic Pt(III) complexes via the homolytic cleavage of the Pt–X bond. Lewis acid sites were found on the surface of the mechanically activated K2PtCl6 salt using the paramagnetic probe method. The sites can be attributed to coordinatively unsaturated Pt(IV) complexes formed via Pt–Cl bond heterolysis.
