Abstract

The structural characterization of a 13 CO-labeled Ir(I) complex bearing an P,N-donor ligand (1-[2-(diphenylphosphino)ethyl]pyrazole), [Ir(PyP)( 13 CO)Cl] is demonstrated using a series of tailored solid-state NMR techniques based on ultrafast (60 kHz) Magic Angle Spinning (MAS), which facilitates correlations with narrow proton line-widths. Our 1D 1 H MAS and 2D 13 C and 31 P CP-MAS NMR spectra provided structural information similar to that ...
