Functional materials design: octahedral tilts in hybrid n = 1 Ruddlesden–Popper phases

The exciting properties offered by hybrid perovskite-related materials have motivated Liu et al. [(2023). IUCrJ, 10, 385-396] to explore the crystallography of hybrid n = 1 Ruddlesden-Popper phases. Their investigation explores the structures (and symmetries) expected to result from typical distortions and gives design strategies to target specific symmetries.
