(a) Evolution of the normalized lattice parameters (and angles) under HP (inset) of the Sr2FeIrO6 structure in the space group I1, and (b) pressure dependence of the volume. Experimental data are represented as symbols and the theoretical calculations as solid lines. The region of quasi-hydro­static conditions up to ∼10 GPa for the 4:1 methanol–ethanol mixture pressure-transmitting medium is shaded in the plots.
