Stable Cationic Dimethyl(hydrido)platinum(IV) Complex

Stable Cationic Dimethyl(hydrido)platinum(IV) Complex

The complex [PtMe2(9N3)], 1, 9N3 = 1,4,7-triazacyclononane, undergoes protonation by triflic acid and, reversibly, even by methanol to form the cationic complex [PtHMe2(9N3)]+, 2, which is thermally stable up to 190 °C in the solid state as the triflate salt. Oxidation of 1 or 2 by H2O2 or by H2O/O2...

Zusammenfassung:The complex [PtMe2(9N3)], 1, 9N3 = 1,4,7-triazacyclononane, undergoes protonation by triflic acid and, reversibly, even by methanol to form the cationic complex [PtHMe2(9N3)]+, 2, which is thermally stable up to 190 °C in the solid state as the triflate salt. Oxidation of 1 or 2 by H2O2 or by H2O/O2 gives the hydroxy complex [Pt(OH)Me2(9N3)]+, which can be reversibly protonated to the aqua complex [Pt(OH2)Me2(9N3)]2+.
