In n = 1 RPP, the BA cations interlaced with one another a result of the interaction with apical I atom (shaded as purple) of floor PbI6 octahedron, wherever a bigger in-plane octahedral tilt and a little out-of-aircraft tilt exist. In the case of n = 4 RPP, the BA molecules adopt a “head-to-head” configuration making sure that their NH
