Typical high-angular-resolution SXRD profiles for PrNiO3 (red open circles) and corresponding Rietveld refinements (black lines) at (a) 10 K for the P21/n (monoclinic) phase, (b) 295 K for the Pbnm (orthorhombic) phase and (c) 900 K for the [R{\overline 3}c] (rhombohedral) phase. Blue lines denote the fit residuals and green bars represent the expected Bragg reflections. Diagrams on the right are structural views from each phase (monoclinic, orthorhombic and rhombohedral).
