T-Shaped Palladium and Platinum {MNO}¹⁰ Nitrosyl Complexes.

ABSTRACT: The synthesis and characterization of a homologous series of T-shaped {MNO}¹⁰ nitrosyl complexes of the form [M(PR₃)₂(NO)]⁺ (M = Pd, Pt; R = tBu, Ad) are reported. These diamagnetic nitrosyls are obtained from monovalent or zerovalent precursors by treatment with NO and NO⁺, respectively, and are notable for distinctly bent M-NO angles of ∼123° in the solid state. Adoption of this coordination mode in solution is also supported by the analysis of isotopically enriched samples by ¹⁵N NMR spectroscopy. Effective oxidation states of M⁰/NO⁺ are calculated, and metal-nitrosyl bonding has been interrogated using DFT-based energy decomposition analysis techniques. While a linear nitrosyl coordination mo
