a Schematic of the n = 2 RPP 2D Pb-I octahedral cages, highlighting the apical and equatorial angle α and β, and the out-of-plane and in-plane octahedral tilt angle ɵ and γ, and bond length dI1-Pb and dI2-Pb, respectively. b Evolution of Δα and Δβ in n = 2 under compression and decompression. Evolution of the Δɵ and Δγ in n = 1 RPP (c) and n = 2 RPP d under compression and decompression. The yellow-shaded area in b, d represents the irreversible deformation region.
