Transition Metal NMR Spectroscopy.55Mn,13CO and55Mn,31P coupling constants of organomanganese complexes: comparison of NMR results from experiments in solution and in the solid state

Scalar spin–spin coupling constants of some organomanganese complexes, Mn(CO)5-n(R)Ln, were evaluated by lineshape analysis from 13C and 31P solution NMR spectra and from solid-state magic angle spinning spectra showing first-order splitting. Consistent results were obtained for favourable complexes, but each method has only limited applicability in the general case. The merits of both methods are discussed.
