Solid-state NMR of LiIn 2 SbO 6 . A wideline solid-state In NMR spectrum of LiIn 2 SbO 6 was recorded by collecting frequency-stepped sub-spectra covering an excitation range of more than 18 MHz (Figure , Supplementary Figures ). In addition to signals from In, the broadband spectrum also overlaps the 121 Sb and 113 In Larmor frequencies.
