a–c The SAED patterns of the NN5SS_1.0Mn, NN7SS_1.0Mn, and NN9SS_1.0Mn samples recorded along the zone axis of the [010], [110], and [110] direction, respectively. The white circles highlight the selected reflections for the bright-field and centered dark-field images in Fig. 2d–f. 23Na STMAS NMR spectra of d NN, e NN5SS_1.0Mn, and f NN9SS_1.0Mn samples. The signals of g NN, h NN5SS_1.0Mn, and i NN9SS_1.0Mn samples along the indirect dimension δ1.
