The discovery of nickel-based superconductors La₃Ni₂O₇ and La₄Ni₃O₁₀ has drawn considerable attention to the Ruddlesden-Popper (RP) phase. In our previous presentation at the Spring Meeting, we reported a new RP-phase oxychloride compound, Sr₃Ni₂O₅Cl₂. In this study, to investigate the general structural stability of this crystal system, we synthesized and analyzed the crystal structure of (Ba_1-xSr_x)₃Fe₂O₅Cl₂, which contains Jahn-Teller-inactive Fe³⁺ ions.
