Molecular analogue of the perovskite repeating unit and evidence for direct Mn^III-Ce^IV-Mn^III exchange coupling pathway.

ABSTRACT: The perovskite manganites AMnO₃ and their doped analogues A_1-x B _x MnO₃ (A and B = main group and lanthanide metals) are a fascinating family of magnetic oxides exhibiting a rich variety of properties. They are thus under intense investigation along multiple fronts, one of which is how their structural and physical properties are modified at the nanoscale. Here we show that the molecular compound [Ce₃Mn₈O₈(O₂CPh)₁₈(HO₂CPh)₂] (Ce^III₂Ce^IVMn^III₈; hereafter Ce₃Mn₈) bears a striking structural resemblance to the repeating unit seen in the perovskite manganites. Further, magnetic studies have establis
