Mn-55, (CO)-C-13 and Mn-55, P-31 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)L-n, were evaluated by lineshape analysis from C-13 and P-31 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.
