The 1H NMR spectra of 8-quinolinolato complexes of Mn(III)

1H NMR spectra are reported for tris(8-quinolinolato)manganese(III), tris(2-methyl-8-quinolinolato)manganese(III) and mixtures of tris(acetylacetonato)manganese(III) and tris(8-quinolinolato)manganese(III). In the latter case, mixed complexes are formed in equilibrium, with only one of the three possible isomers of acetylacetonato bis(8-quinolinolato)manganese(III) being present in detectable amounts. The spectra were assigned making extensive use of selective deuteriation.
