Prolonged evacuation of [{Pt(CO) 3 } 2 ] 2+ (1) , the first homoleptic, dinuclear, cationic platinum( I ) carbonyl complex, results in reversible disproportionation. Complex 1 was formed by dissolution of PtO 2 in concentrated H 2 SO 4 under an atmosphere of CO [Eq. (a)], and completely characterized by NMR ( 13 C, 195 Pt), IR, and Raman spectroscopy.
