Evolution of the experimental and theoretical (a) Fe—O and (b) Ir—O bond distances under HP of the Sr2FeIrO6 structure in the space group I1. Experimental data are represented as symbols and the theoretical calculations as solid lines. Experimental Fe(Ir)—O bond distances represent the Fe(Ir) atoms in the atomic sites 2f(2g) with a fractional occupancy of 82.6%. 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.
