Figure 1

Single-crystal X-ray structures of (A) (MA)PbBr3 (MA = CH3NH3+) at ambient pressure (space group: Pm3̅m) and 1.7 GPa (Im3̅) and of (B) (MA)PbI3 at ambient pressure (Fmmm) and 0.7 GPa (Im3̅). Turquoise, purple, and brown ellipsoids represent Pb, I, and Br atoms, respectively. Disordered iodides and MA cations omitted for clarity. Thermal ellipsoids are drawn at the 50% probability level.
