文摘

The n = 3 Ruddlesden-Popper phase Sr₃LaFe_1.5Co_1.5O_10± is capable of sustaining O contents as low as O_7.5 with a mean metal oxidation state of +2 and three coordination at the central site in the trilayer of originally octahedral transition metal sites. The shortening of the axial bonds to the flanking octahedral layers stabilizes the low oxidation state and consequent unusual low coordination number of the Fe²⁺ and Co²⁺ cations within the extended structure.
