Abstract

Inspired by the ferromagnetic coupling in the cubane model CaMnᴵⱽ₃O₄ of the oxygen-evolving complex of photosystem II, 3d–4f mixed-metal DyMn₃O₄ clusters were prepared for investigation of the magnetic properties. For comparison, YMnᴵⱽ₃O₄ and YMnᴵⱽ₂MnᴵᴵᴵO₄ clusters were investigated as well and showed ferromagnetic interactions, like the calcium analogue. DyMnᴵⱽ₃O₄ displays single-molecule-magnet properties, while the one-electron-reduced species (DyMnᴵⱽ₂MnᴵᴵᴵO₄) does not, despite the presence of a Mnᴵᴵᴵ center with higher spin and single-ion anisotropy.
