a 13C{15N}REDOR NMR pulse sequence. b The experimental {13C}15N REDOR dephasing curve of the precursor 13C,15N-MAI powder. The dashed line is the REDOR curves simulated using the length of carbon-nitrogen bond of MA molecule reported in X-ray crystallography research33, 48,49,50,51. c The {13C}15N REDOR spectra at the 2.4 ms dephasing time of 13C,15N-MAI powder, 2D (PEA)2(13C,15N-MA)Pb2I7 (n = 2), 2D (BA)2(13C,15N-MA)Pb2I7 (n = 2) and 3D (13C,15N-MA)PbI3.
