Figure 2. (A) Asymmetric units for molecular structures of (MP)PbBr3 collected at 350 and 193 K, respectively. 1D packing structures of (MP)PbBr3 in the (B) HTP and (C) LTP. Order-disorder changes are clearly observed during the phase transition. 1D: One-dimensional; HTP: high-temperature phase; LTP: low-temperature phase.
