Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Mix and match</bold>: Topotactic hydride reduction allows the first synthesis of the fully reduced parent phase, Sr₄Fe₆O₁₂, of the important family Sr₄Fe₆O_13±δ. The structure provides a rare example of pairs of edge‐linked tetrahedra, in this case containing a random arrangement of Fe^II and Fe^III centers at 300 K. On cooling, charge order occurs so that each pair of tetrahedra has one Fe^II (white) and one Fe^III (black) center.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1xpsz9pc" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
