Coupling Dy3 Triangles to Maximize the Toroidal Moment

A hexanuclear dysprosium(III) compound constructed by two Dy3 triangles in an edge‐to‐edge arrangement perfectly retains a nonmagnetic ground state and single‐molecular‐magnet behavior. Such an arrangement and the strong couplings over a μ4‐O2− ion stabilize a similar arrangement of toroidal moments...

Summary:A hexanuclear dysprosium(III) compound constructed by two Dy3 triangles in an edge‐to‐edge arrangement perfectly retains a nonmagnetic ground state and single‐molecular‐magnet behavior. Such an arrangement and the strong couplings over a μ4‐O2− ion stabilize a similar arrangement of toroidal moments in the ground state, thus maximizing the toroidal moment of the complex.
