Oxygen octahedral rotations have been measured in short-period (LaNiO${}_{3}$)${}_{n}$/(SrMnO${}_{3}$)${}_{m}$ superlattices using synchrotron diffraction. The in-plane and out-of-plane bond angles and lengths are found to systematically vary with superlattice composition. Rotations are suppressed in structures with $m>n$, producing a nearly unrotated form of LaNiO${}_{3}$. Large rotations are present in structures with …
