The paramagnetic one-dimensional H-1 NMR spectra of twelve Ln(III)Na(I)(OAc)(4)[12-MCMnIII(N)shi-4] complexes, where Ln(III) is Pr-III-Yb-III (except Pm-III) and Y-III, are reported. Their solid-state isostructural nature is confirmed in methanol-d(4) solution, as a similar pattern in the H-1 NMR spectra is observed along the series. Notably, a relatively well-resolved spectrum is reported for the Gd-III complex. The chemical shift data are analyzed using the "all lanthanides" method, and the Fermi contact and pseudo-contact contributions are calculated for the lanthanide-induced shift (LIS). For the Tb-III-Yb-III complexes, the pseudo-contact contributions are typically 1 order of magnitude higher than the Fermi contact contributions; however, for the Gd-III complex, the Fermi contact is the main contribution to the paramagnetic chemical shift. For the methyl protons of the axial acetate (-OAc) ligands, the LIS is opposite in sign, with respect to that of the aromatic salicylhydroximate (shi(3-)) protons, because of structural rearrangements that occur upon dissociation of the Na-I cation in solution. The calculated crystal field parameters (B-Ln) for the Tb-III (360 cm(-1)), Dy-III (250 cm(-1)), Ho-III (380 cm(-1)), Er-III (410 cm(-1)), Tm-III (620 cm(-1)), and Yb-III (380 cm(-1)) complexes are not constant, likely as a consequence of the inaccuracy of the Bleaney's constants and, to a smaller extent, the small structural changes that occur in solution. Overall, the metallacrown scaffold retains structural integrity and similarity in solution for the entire series; however, small structural features, which do not affect the overall similarity, do likely-occur.
